Got a pair of these for a Tamiya semi build. can't speak for durability since my RC's are seldom used and never driven hard. So far, so good. Price was right and was different then the usual servos I use (which is what I wanted).

Really nice and powerful servo!

It is very fast and has a lot of torque though, it is very power hungry so I ‘m not using it anymore. And I’m pretty sure I can’t get a refund for this reason so it will be sitting in my room but overall it is good but make sure you can support it’s power consumption.

Cys has proven itself as an affordable but quality servo! I love it!

Good and cheap digital servo. CYS has yet to fail me.

It works great I´m very happy. Asiatees Rocks.
