FL330 Wearable Blood Oxygen Band with Ring Sensor & Free O2 Records, Smart Fitness Tracker & Heart Rate Monitor (Free APP and PC Software)

I've had this device a couple of months now and love it. I ordered it while waiting on a CPAP machine, and it's comfortable to wear. It has a sleep report that you can download and review that seems accurate - I see the times I've been up with the dog, etc, because there is a break in the recording. The vibration I have set to 90% and level "Strong" and that works well for me; it wakes me up to breathe but can go right back to sleep. I can use it two nights before charging.

The watch is awesome. I have trouble with oxygen levels drop below 90%, and some time below 80%. until doctor and I can figure this out this watch vibrates my finger if oxygen goes below 90% in my sleep. Now I can't use because I cannot find a matching charger. Try to contact seller twice, they tell me any charger will work. not true. I am still looking for a charger. The produce is worth every penny, needs to have a more user-friendly charger.

I don't review products as a rule. But with forty plus years of product development behind me, I feel compelled to give credit where credit is due.This SpO2 monitor is one of those products that just makes you feel that someone took great pride in it's design and production.Accurate, ergonomic, flawless connectivity, and an app that works. I recommend it to anyone in need of a no nonsense device to do an important function.

Given how many Chinese products are these days, I didn't have terribly high expectations for this. But the built quality, documentation, and how it generally works are pretty good. The Android and PC software are both a little confusing, but I've seen way worse.Really my only complaint is that I'm a light sleeper and in a dark room, the display on the unit seems very bright. It would be great if there were some way to dim it, or if the unit had a light sensor to auto-dim it in dark rooms. Putting electrical tape over the display isn't a very high-tech solution but it fixed it for me.

I don't recommend anything from this manufacturer FACELAKE. I started having malfunctions and reached out to them for a potential replacement. They asked me via email to send a copy of the order from their website or Amazon.They asked for a video to be submitted and pictures. I did just that per their request. They told me after a week that they couldn't back up their product because I purchased through AMAZON.They could have restrained themselves from wasting my time with the back and forth and request for videos, etc. They knew that they were going to take ZERO responsibility of the item if it was purchased from any other sites other than theirs.I bought 2 additional devices last minute as I was going on trip but after receiving their response these things are going back.Dont support your products? You dont deserve customers.

Started off OK but no software and it stopped being accurate in just months. I have no idea if it every was accurate now. I had to struggle with seller to get software and it does not go to this so no idea if I can recalibrate it. I seemed to be getting worse and worse and tonight it was saying I had a PulseOx of 80 when I was wide awake and fine. I compared it to another finger meter and I was fine. This item was giving out false data. $200 should last longer than 2 months.Bad data might be worse than no data at all.

I like the app and the alarm buzzer on the finger sensor.

I bought this for my husband, he loves it! He has learnt so much about what happens during his workouts and while he sleeps!He believes this is very accurate!
