SKYRCGSM-015 GPS Enabled GNSS Remote Control Speedometer and Altimeter Data Tracking Device for Vehicle, RC Car, Boat, Plane, Rocket, and Quadcopter

I bought this item to attach to my RC Aircraft the spitfire MK 24, twinotter, tundra, A-10 thunderbolt, and my F-16C Falcon jet to record the speed, altitude, milage. It works great for that I had to paint the sides of the unit so it will be easier to find if I crash. it works great and would buy another if by chance I lose it,

I don’t get the the negative reviews, this gps does what it’s supposed to do. It feels a little cheap I would suggest wrapping it with some electrical tape to make it more durable that’s what I did

Battery dies fast not worth the money , saw another review stating same thing ,well it’s true

Got it quick. Works incredibly well with my rc car. Very accurate readings. Great gadget!

GPS works fine. I use it in my Rc boat. However it is not waterproof. Gets moisture in the display and you have to dry it out for a day or two and then it works again

Well this thing is cool. It's actually better than I expected and I like how it records the data and your able to pull it up on your computer to see. I felt like app install was a little sketchy but everything is fine and I would reccomend it to anyone that wants to record and go over your radio controlled runs that this unit will make you happy.

Weak on original battery. Doesn't work, at all, on replacements. [Editing to add that I did hear from the seller with questions about my disappointment. Not sure anything was resolved.] I don't understand how this thing can be sold for more than the same brand product much higher quality and capabilities.Don't waste your 70 bucks or get their better one, (for less money), or a competitor and there are plenty, especially for bicycles, in this price range.

This is a great GPS pretty Accurate very light weight Easy to mount and Use.Highly recommend
