You can't beat the price, but you get what you pay for.  The overall construction is good, but keep in mind that it is plastic through and through.  There is little padding for your timepiece, which is okay if you are careful.  The programming works well and it is silent, however if you have heavy watches the motors will make a clicking noise.  It is not that loud, but it is certain to wear out.  I use this for my Rolex Date and a U-Boat Classico.  Both keep excellent time, but when it winds the motor for the U-Boat clicks once with each rotation.  If you have large, heavy watches I would not recommend this product as it will surely wear out.  This is my first winder and I am happy with mine; for $50.00 it works well and when it stops working I will invest in a quality winder.
