Customer Ratings & Reviews

So the first time I got the bracelet I thought it had a slick and slim design that was comfortable for me, but the customise options with this product is very low. On another note for the first week or so it would work and then after that the connections would drop between my phone and the band, and once I would get it re-paired with my device it wouldn't send me notifications on the band, which is one of the main reasons I bought this, I'm not on my second band and it has done the same thing to me. I plan to return it soon and I probably will not be getting another one until Razer fixes these problems, other problems that I have encountered with this product is the sleep tracker doesn't work properly, along with the pedometer. Please Razer fix this product and give it more customisabillity, this product has so much potential, it only needs a bit more work.

The Nabu X is only $50 and it shows the double tap to show your goals barely works and it sometimes doesn't keep track of sleeping progress. Its a good health monitor for the price but it has its quirks. I would recommend it if you don't mind it being unresponsive some times because the double tap you really have to tap it a lot and in the right spot for it to work. Its a good health accessory that doesn't cost $150+ for a fitbit. (if you wanna spend that much just get a Moto 360 for android and iPhone as android wear is coming to iphone this fall. As the moto 360 is beautiful and has more functionality than just tracking steps heart rate and sleep.)

The Nabu-X has a great battery life. This makes it a great sleep and activity monitor. The software is very basic, but it does sync with Google fit. It has a strong vibrator so it will get your attention when a call or an alert comes in.. My biggest complaint is that it disconnects from my Galaxy S3 all the time. It is not reliable because of this and so on don't recommend it. Perhaps it does better on a newer phone...

The band does a good job at tracking steps. It measures sleep by tracing the time the user stops moving with the band on after a certain amount of time, I suppose. It also measures calories although that relies mainly on the information you put into the app along with how active you were that day. The app itself is finnicky and you need it in order to use the band. It seemed to work fine but reset itself for some reason when I took a trip to a different state (PA to FL) Not sure why, but lost some data. Still, it's a cheap way to keep track of activity.

It was a great fitness tracking bracelet. Counted steps and miles accurately, although I had a hard time changing kilometers to miles, until the new update. I was personally terrified to put the bracelet in water even though it is water resistant, I found that out the hard way. The only reason I gave it 4 stars is because the Bluetooth it uses on my phone, which is an iPhone 6, kept disconnecting at random times and would not reconnect until you went into the phone and connected it again. But I would 100% recommend this to anyone, especially to people who don't want to spend the money on a Fitbit.

I purchased this product solely for the ability to get notifications to my phone while it was on silent. It does a great job for that task. Aside from that though. The pedometer though isnt the best. It doesnt keep up with the steps at time at a walking pace at times. Aside from that though, I recommend the purchase of this item for notification purposes first and foremost. But not as a sports utility band.

While I purchased this product mostly for the phone alerts, it can do much more. The packaging said it would work with iOS 7 and higher. This is not accurate. I contacted customer service and they were very responsive and helpful. They were unable to resolve the issue, but we were able to upgrade the phone and the operating system through our service provider. My father is hearing impaired and I bought him this to notify him that his phone was ringing or receiving a text. It works as expected (now).

Keeps track of calories and steps pretty well. Good battery life. Good price.

This was a gift for my cuñada. She loves it. Wears it every day and constantly tells me how much she's walked. Works like it should. Not as good as something with GPS but she likes it.

I have tried many fitness bands over the years and may not be the worst, but it was certainly not the best. The worst part of this product is the companion software you use with it. It feels rather cluncky and halfbaked.

Great product although still needs to have work done to it.

A fun way to track and keep up with every day steps and physical activity. My son loves the different color lights. Fun!

Great item for the price. Works great excellent battery life last for 5-7 days.

This product is great for starters. Love the battery life!

I use the Nablus x in conjunction with my misfit for step tracking in my excercise routine. I got mine on sale for 30. Well worth it.The app has nice UI layout. Simple and to the point. Can't go wrong with this purchase.

I use this as an alarm to wake up as to not disturb others who are still trying to sleep, it works really well for that. I have tried to wear it as it is intended and found that it fell off a lot. I really only wanted the alarm feature anyway so it is fine for me.

I got this band clearanced at my local store and two days in, I knew why. This band as potential to be good but Razer locked it down so you can only use there software with it and they dropped support for it. I can't really do much with it now but it vibrates when I get a message so I guess I got a cool wrist massager!

I really like this tracker the price it is I only charge it once a week and never take it off works great with the app better on Android then iOS though

Does all the great basic features of a smart band. Very good product for the price point. Love the long battery life.

You will have to read the instructions to get this one started. But once you get it charged up and going it's a piece of cake. Very easy to use
