Have had 2x remote controllers stop working!! And the 2x battery have distorted and will not allow the waterproof door to close.No give and take in the battery compartment.Unit got so hot ,almost burn't ones hand .As for service the agents have a lot to learn!!

Went to set up the SPRY + and found the remote would'nt charge.Blue charge light would go for 20 mins then blink. Waiting for a replacement,would think that it was tested at the factory and going before dispatch.Its not the only one they need to return.

First of all, it is waterproof and very strong. Second, remember to debug the remote control buttons before the flight

It's so easy to set up, Just couple of minutes to make everything hooked up.

Good quality, works great, could use a slightly updated and improved design
