Query: Wish I had read the reviews before I ordered

I ordered 3 of these card shufflers. One works just fine. On the second one the spring tray doesn't work and on the third one the left side only shuffles intermittently. Obviously they aren't checked to see if they are even working before they are shipped out. I would pay twice as much for a sturdier model.
