Rated 3 out of 5 by MaverickDH Crisp, easy to set-up shifting, but with weak spring tension.
Using these with a X4 trigger shifter results in accurate and repeatable 8 spd shifting due to its simplistic 1:1 actuation ratio. Along with SRAM's direct route cable routing, the installation of this unit is a breeze. The adjustment screws have large heads and when used with a proper size screwdriver don't feel as if they will strip anytime soon. This is completely the opposite of the comparable 7-8 spd Shimano Acera M360 unit, which has much smaller screws for the high and low stops. However, the same cannot be said about the bolts holding the jockey wheels to the cage, as they are much smaller than the ones used on the M360 and are prone to stripping. Also, for those considering upgrading with aftermarket 11T jockey wheels, the bolt holding the guide pulley is offset from the centerline. This will require re-adjustment of the b-adjust, which may annoy some.
Moving onto my real complaint about this unit, the spring tension is considerably weaker than the Acera M360 RD and thus results in a lot of chainslap. For a brand new derailleur to have this much chainslap compared to a four month trail-ridden M360 is really something! I cannot imagine how bad it will get if it even manages to survive on my bike for more than a month. Not due to durability issues, no not that, but probably because I will bash it clean off with a hammer :/
To be fair, neither the M360 nor the X4 are really designed for anything other than “recreational” use. For the average commuter both derailleurs will offer very similar shifting performance, with the X4 beating the M360 in this category due to the 1:1 actuation, better cable-routing, and cage design. The X4 also beats the M360 in terms of durability, as the main adjustment screws are stronger with exception of the jockey wheel bolts. As closing remarks, for commuters who do not need stiff springs and want to experience better shifting, the X4 is a great choice. However, for cyclists geared more toward trail-riding or those who want to venture into heavier riding disciplines, the M360 might be a better alternative within this price range simply due to the stiffer spring.

Rated 3 out of 5 by Jaiz18 Emergency budget repair
I bought this mech as an emergency budget repair as I destroyed my other 4 days before an event and it worked well, Im actually still using it and will continue to until this one dies.
Can't fault it for the price.

For the price - you cannot go wrong with this. Had it for several months now with some brutal use in between and still shifting really smooth.

Rated 5 out of 5 by Anonymous Very Precise mech!
I've bought it to replace an old Shimano STX. I've never seen a so fast and accurate mech like this. I've got a Shimano Tiagra mech in my road bike and I'm thinking about replace it with a Sram Rival or some other mech. Don't forget to combine it with Sram X4 shifter btw.

Rated 4 out of 5 by Anonymous хорошо
Лучше ACERA 360 ,не лучше ALIVIO 410.Переключения "точные". Есть недостаток-ограничитель на малую звезду кассеты не участвует в настройке(выкручивается на всю ,а то цепь будет задевать соседнею звезду).Новые ролики вращаются не охотно-туговатый ход,заметно по сравнению с любым шимано.

Rated 4 out of 5 by Anonymous Great product, great price
Had hoped to go for something a bit better, possibly the x-5 to match my shifters but when I saw the price, it seemed foolish to pass this one by.
Been on the bike a month now. It looks the biz (not often that you can say that for cheap kit) and it shifts great. Overall, I'm very happy with this product and would recommend it to anyone looking for quality at an affordable price.
