Product review (1 stars): I would recommend getting something else even if you have to pay ...
When it's working as intended it works really well, but the design has some serious flaws in it.

First, the plastic hinge does not hold up well to the rigors of a washing machine. Every 2-3 loads the float will come completely free of the filter. Once that happens it will not capture any lint at all. This has also caused a crack at the base of one of the arms which causes the float to slowly fill with water.

The float itself is also just two piece of plastic that clip together and every few loads the top will pop off.

Also, as others have mentioned the mesh filter will fall out after several loads if you do not secure it. The plastic ring is actually two parts and the mesh is sandwiched between them, but again the rigors of the washing machine will cause it to come undone. I used a number of cable ties to secure the mesh filter to the float.

I would recommend getting something else even if you have to pay more for shipping (I got mine as an add-on). I've only had this one for a couple of months and I'm already to the point where I have to fix something after almost every other load.
