Bought this for a replacement for my Giant Mtn. bike. I am not a rough/tough rider; more recreational. I was a little concerned because of the price vs. the quality... Well to my surprise it is working great and fit perfectly. I compared it to my friend's replacement seatpost which he paid double what I did and the Promax was just as good. The finish and machining/screws/connectors were fine.A good buy for the money for a replacement post. Received it early too!
