Alesis Vortex Wireless 2

I bought this almost 2 years ago and had a lot of fun with it. Sadly only behind my desktop.
It would be a solid 5 star rating, if the wireless function worked. Which it DOES NOT.
It's really hard to be fair because of this... I love every single other aspect of this, but since being wireless is a core feature of this instrument and it fails at that, it's basically a total fail and I cannot comfortably give more than the minimum amount of stars. Although I really would want to.

It's a shame. Such a good looking keytar with a good amount of faders and pads.
But I get annoying hang notes every time I use it wirelessly, that render it basically useless for live gigging.
That problem occurs a lot of times, as you can see on various forums on the internet and the customer support was no help either.
Also the pitch wheel doesn't snap back to 0 a lot of times, which gives off a detuned terrible sound.

For an instrument, that has "wireless" in it's name, that's a damn shame.
I have to use it with cable now.
I love playing keytar but I really regret buying this one.
Do not recommend!
