I bought 2 of these. Hopefully they last. The plastic they use can be prone to cracks and eventually break at the lever where it has the most compression stress. For the price, it's ok.
I waited a long time for this to arrive and it did. Better late than never. Did the postman hitch-hiked his way here? I feel that the plastic lever can crack or break if it is over-tightened. Looking at it right now, it looks like it will even break if I drop it to the hard floor. But for the price I paid, it's alright. Just be careful. Thanks to seller!
