I have two very reliable bp devices and so i put the one on my wrist, the other is a pump up cuff, put that on too and my new ck11c. The two bp devices were very close in their blood pressure measurement but the ck11c, was way way off. The bp function is of no use. Now i’m wondering about the other functions????. 3-stars because the watch is nice. This device is truly too large for a woman.

I appreciate how well thought out notifications are configured, all notifications can be set so that when you sleep they won’t go off. Bp is way low, but i didn’t expect an ekg style measurement to be accurate. Everything else seems to work as advertised. When i unpacked mine, the default clock was analog and it took paying attention to the manual on how to switch it to digital (2 versions). Bring up the clock, press and hold the select area on the face for 3 seconds and then you can choose which clock version. The ‘leather’ band is well, uncomfortable and sweat inducing. Charging time is short, about an hour and life so far is amazing. It integrates perfectly with apple health – i was very happy with this and it’s a snap to setup. The main issue i have is that it’s impossible to see anything in the sunlight or even bright environments and i can’t find a way to make it brighter.

This product sucks it worked for 3 days then the battery diesand does not charge any more battery is died. Now whatupdate :after troubleshooting luckyruby sent me a new replacement smart bit. No questions askedthis company and may are 5 stars very good communication skillsvery good supporti will continue to purchase and recommend products from themchristos.

Love the convience of being able to get bp and oxegyn whenever i want.

I like the ease of use and setup.

After charging i had it synced to my phone in minutes. I am very happy with the over all look and performance of it. I purchased the bronze colored one. If it does disappoint in the future i will change my review. Like i have said, so far all is well.

Was everything that was described. A great product for the price.

Comments from buyers

“Better product from helpful company
, Took a while to figure out but it works!
, Well thought out, 1 major issue

This product and company deserve a positive review, although i rarely submit reviews for anything. The ck11c fitness tracker and watch bracelet is definitely better than two other fitness trackers purchased before this one, which use different software on my iphone. All functions are convenient and mostly automatic. For health i especially like using its automatic sleep monitoring and presentation and its walking distance tracking. Its heart measurement functions are helpful to have available, although i wish they were more accurate compared to standards i use (only reason for rating of 4 instead of 5). Heart accuracy is about the same as the other two similar trackers tested. Its clock/watch and other digital functions are more convenient than expected. Viewing text messages and who is calling my cell phone are very nice features, if i look quickly enough. Ability to buzz my iphone for quickly finding it is a nice bonus.

Accuracy of the readings are the most important feature of this fantastic watch. My doctors love that i have this watch, they can easily see (on my cell phone) my history of readings of my bp, 02, heart rate and more. For me it is like having a vitals security blanket.

Took about an hour to figure out how to use the watch and pair/bind. Pairing the phone to the watch was easy but you have to open the app and bind the app to the watch. It didn’t want to bind so i had to open the app and read the faq. Said to turn watch off and back on. Had to read the faq on the app again to figure that out. Once i turned the watch off and back on it paired and connected with the app. Once paired the time is set automatically. I scrolled through the functions and checked my blood pressure and heart rate and they were pretty accurate.
