Bests & Worsts Reviews from Amazon

The whole premise for this product working is to inflate a tube that the mat roll up on to keep the puzzle in place. It casually advises to ‘use a hand pump’ (NOT provided) and it’s not a lifesaving device. (WHY?!) You can’t blow the tube up by mouth. The cheap plastic opening isn’t open. It’s all one pieces- with the ‘opening glued on!! Don’t try piercing it open... just throw it away in frustration. Total piece of crap.
