CNCLOL Bike Rear Derailleur 10 Speed，Bike Shifter 10 Speed for Shimano/sram

Does what it sais on the pack 👌👌

Upon receiving the derailleur the first thing which jumped out at me was that it Was made ENTIRELY of plastic besides the internal spring and travel adjustment screws (which where in fact just that - two wood screws that you would use to attach two peices of wood together! Not to be controlling a vital function of any derailleur! And these two screws just screwed through the plastic frame of the thing with ZERO sort of reinforcement metal plate to give it a modicum of durability. It was also lacking any cable tension adjustment barrel threading on the top end. The shifter although obviously made to a price, did actually perform its designated function without any notable incidents. but the deurailur basically broke into 3 pieces whilst I was riding down the road in heavy traffic which could have been very nasty had it not been just for pure luck . Absolutely TERRIBLE build quality, unfit for purpose. I used it twice and this is what happened. Hard earned money thrown down the toilet that ICan't afford to lose. I haven't bothered to contact the seller as I see it as an excercise in futility.

Wouldn’t touch it could shift properly into half the gears save up and get a better shifter and derailleur

Shifts good if set right.
