I opted for the Kam Snaps, because the customer reviews of other well-known brand had failed not very good. How many have written before me, it is really easy to use the pliers so that in no time pushbuttons can be fitted. I have now mounted a few buttons, but have to say that, once the substance (or the stitched layers) is a little thicker, not hold the buttons! At least it was for me like that. You can then correct and nothing has to pinch sew everything. Therefore, a point deduction! But it is in the description of 2.5mm (if I am not mistaken) - I can not tell you how much more mm had my cloth in thickness. Otherwise, the purchase is worthwhile.
