I had no luck with pedals from AliExpress, do not think buying from Asia direct is worth - considering you get Shimano or similar pedals at decent prices.
Failed badly with Xpedo RF-S1 (SPD), very difficult to release.
Also ran a pair of SYUN-LP R31 (SPD SL), heavy design flaw: only one ball bearing in the center of the axle and a bushing near the crank arm.
The bushing wore out in no time, resulting in a loss of seal and pedal play.
Pedals from AliExpress: never ever again...
