Report on CMS50E Pulse Oximeter

Just a couple of things I forgot.

1) Thank you Arizona-Willie for your review.

2) What is meant by "wireless" as well as USB download? I looked at all of the specs I could find, but it appears that they all copied one another or the manufacturer's notes. I did not see anything about Bluetooth or 802.11 so I suspect that it may be the old-time infrared link hardware. Is that correct?

I suspect that its not "real" just yet.

The lack of detail compared to some of the other CMS range models suggests that its not on the market at this time, and the photos have the look of a prototype unit.

The big issue with "wrist" pulse/oximiter units is how much a replacement fingertip sensor will cost..... as most users will manage, sooner or later, to damage the relatively fragile type of sensors that many of the wrist units use!

The finger tip clamp style units, while a bit more intrusive tend to be much more robust.

Cheers,

Bill,
That's in-part why I chose the Nonin 3100, plus its 3-year warranty. Of course, I didn't read every word of the Nonin warranty coverage details. And that its sensor plugs into the wrist oximeter -- interchangeable and easily replaceable albeit not inexpensive. Replacing a sensor is far cheaper and less hassle than replacing an entire unit.

Too, I wanted to use Profox Standard Version software, which can work with over forty (40) brand / models of oximeters. It's the upgraded version instead of the model / specific version that comes bundled with many oximeters sold online. That offers me more versaility over the long haul. And it's apparent that I won't ever be absent a need to monitor my oxygen levels during sleep.

I don't doubt that CMS products and other brand / models are accurate and reliable, but I value product versatility, warranty strength and duration and company history in addition to product design and features.

But the CMS-50F wrist-worn unit appears to be very attractive in design with a fantastic price. Of course, the details of its usage parameters need to be known.

But for an OEM sales price of only $200 for a wrist-worn unit... I'd say it has the potential to be a consumer-use winner. Though, currently the CMS data-logging units use their proprietary software only. That's probably subject to change too, in time.

Nodzy.

I would also like to add my thanks to Arizona-Willie for a well writiten and comprehensive report. My hope is that the CMS-50F is indeed on the market and, if the specifications match those of the CMS-50E and software is as reported by Willie, it will be of definite interest to me. I see no reason why they would not, but without details we're simply guessing.

In an effort to try to get more information on the current status of the 50F and more complete specifications, I sent an E-Mail to DigitalDiscounters this morning requesting the same.

At the very least, response time to the reply (if any) will tell us a bit about the customer service of the company.

I will keep you posted on the outcome.

New to this group, so please forgive any etiquette breach.

Contec Medical has several web sites. On at least a few of them, http://www.contecmed.com/cart/product_show.asp?id=281 they supply a contact telephone # in the US and a chat service.

I called them to check into the CMS50E and 50F (wrist worn unit). According to what I think I was able to understand from the rep's Chinese English:

1) The CMS50F, which is shown on their and Digital Discounters' web sites, is not available. I have visited Digital Discounters (http://digitaldiscounters.net/product.s ... oductId=38)

2) The alarm supposedly DOES work with the memory mode engaged (I emailed the rep this site's URL so he could read your comments himself)

3) The units may be purchased from the manufacturer direct, though personally I'd pass on this idea.

4) He says the RF unit won't be available for a few weeks, and then will be available as an option.

Lastly, I have a problem with a site like Digital Discounters, that gives no address or telephone number.

I'd encourage at least one of you check my understandings with their rep. Maybe we could get some other questions, such as about their software/firmware) answered.

Dad...
Thanks for the information. I wonder when and if the 50F will truly be available...assuming you and the company rep actually understood each other.

I'm in total agreement with you on your assessment of digital discounters. I share your skepticism when no address, in particular, is provided. They do provide a toll free number but no address. I have a strong suspicion that the site is offshore...perhaps Hong Kong or China itself.


I'm curious what, if any, the response to my E-Mail turns up. If it's in poor English that will provide a clue.

Digital Discounters... has the appearance and skimpy offerings similar to a company I dealt with online two years ago. They were in New York, ripped me off in multiple ways.... and it took me over a year, and dozens of hours of effort, to get my money back.

Though the one I dealt with did have phone numbers posted, but buried, in their site. They also separated and segmented their returns policy and purchase policies across about six (6) non-associated site pages... ensuring that unless the buyer is a diehard info-sucker they wouldn't find all of the "got-cha's" they had buried... like land mines.

It worries me that Digital Discounters is listing the CMS-50F oximetry product for sale that isn't even on the open market.... according to CMS rep's.

Sounds to me... like a float-on-the-money-of-suckers affair.... like the company in NY I dealt with. But... ... I could be wrong.... maybe.

A new wrist unit. Anyone tried it?

here's another one:

http://www.choicemmed.com/productshow.a ... parentid=2

I wrote to the distributor and they offered to sell me samples at US$120 each, plus shipping I assume. Looked interesting. If someone wanted to become a distributor, this might be a good product. Who knows? Not me. They emailed me better pix and more info as well, but it's a jpg image so I don't know how to upload that here. I could forward it to an email box though if anyone was interested.

The previous post comes from Contec. It requests suggestions for product improvement.

Received a reply to my inquiry to Digital Discounters and I give them credit for being both prompt as well as honest on the 50F's availability. Inquiry was sent yesterday morning inquiring as to whether item was actually in stock...and specifications or .pdf copy of instruction manual if available. Their response:

Thank you for your inquiry,

I do not carry the CMS50F in stock. The last I heard from contec was that it is not available yet. I can contact them tonight and find out if they are ready. They do make the CMS60C unit that is a small credit care size, but about 1.5 inches thick. It has a finger clip and it is ideal for overnight oximetry. I comes with usb cable/ac adapter for charging and connecting to the pc and the software on cc. This unit sells for $225 as well. I will let you know about the CMS50F once I know.

Thanks

Evidence does suggest that the 50F will be forthcoming ...hopefully contecjames1 can confirm the if and when. It would appear that D Digital jumped the gun in advertising the product and that scores no points on this end.

D Digital does list an address in Hemet, California...you have to go to "terms and conditions" to find it. They well may be a totally reputable company. Since the response to my inquiry was from a "hotmail" account my best guess would be that they are a small business acting as an intermediary between companies such as Contec and the customer. Since a "Google" on the company provides no information pro or con, I would also guess they are relatively new. However, before anyone would consider doing business with them, I would strongly suggest that they page down and click the "terms and conditions" link at the bottom of the page. In a rather large nutshell, D Digital may change or modify availability and pricing without notice, cancel orders at its discretion, and provides no warranty of any kind for products sold. Any risk of loss is transferred to the buyer once the product is delivered to the shipper. Personally, I would be willing to pay somewhat more for a product to guarantee availability, pricing, and delivery.

The, hopefully forthcoming, CMS-50F still remains of interest to me...especially if it is available for anywhere near the Discount Digital quote. Perhaps Echo will carry it. Per previous posts, the newly found availability of others into the market is a good thing. Competition can only help the consumer where price, features, and quality are concerned. The market has remained a near monopoly for some time.

This is a followup. In my earlier posts, I noted that there had been a sporadic connection between the oximeter and the supplied cable which made it not work unless it was seated just right.

Well, that got worse until, only 3 weeks after having bought it, it stopped being able to upload data.

Moreover, Echostore, the seller, has for the last 10 days refused to reply to my requests for service, even though they were initiated within weeks of purchase, and even though they claim they offer a year's warranty. Six emails have now been not replied to, plus I have now phoned them at their given phone number for 2 days running during their ostensible office hours, and get a recording that "the party you are calling cannot anser, leave a message".

As of the moment, I would caution people away from both the oximeter itself, which lasted less than 3 weeks even with gentle use, and especially with Echostore.com as a seller. Beware! I'll update this if there is any change in the situation.

Just a quick note... this unit works well for me. My doctor was delighted with the report it generates. The installation is a NIGHTMARE and you do need the installation disc. That EchoStore place sent me mine. This model clips on to your index finger. After putting it on, I put a strip of surgical tape all the way around the outside to keep it on. Do I recommend it? It's a lot of $$ to spend for an item that does 1 thing. As I've said, the installation is horrid. But I am satisfied with it. Cheers!

coconut,

Please keep us informed as to what you find out re EchoStore. I have had my CMS-50E for a little over two weeks and have not had any problems other than with the documentation. I have even dropped it a couple of time from my rather high bed and put it back on after hearing the "slipped off" alarm and it still keeps on tick'en.

Hopefully EchoStore has not disappeared. One of the reasons I purchased was the warranty.
