Razer Hunstman Problems

So I've had the Razer Hunstman (not Elite nor Tournament Edition) for about 2 and a half months now, and the entire time of having it I've had problems with it. One problem is that keys being pressed will randomly keep on holding for at least a second after I let go sometimes. My only assumption is that I let go too quickly and the switches can't register me letting go. This happens while I'm typing and playing games. Another problem I had was that if I clicked 2 keys at the same time, sometimes one of the keys I pressed wouldn't work. If I had to click 2 buttons on this game at the same time, one of them doesn't activate sometimes. And, my last problem with it, is that I feel like it stays held longer after I let go, for every press. My keyboard before I switched to this (Razer BlackWidow Chroma V2, which I believe isn't on the store anymore) definitely let go right as I let go of the key, or at least, it lets go sooner than the Razer Huntsman's key release. With me playing rhythm games, these problems really get to me, and the holding after release for way too long problem causes deaths for me where I have to not fall off something on other types of games. So I don't know if this is a general problem with the Razer Hunstman, or if it's just a problem with mine. Either way, I'm thinking of getting a different keyboard, unless someone can fix this problem for me. Thanks for reading!
