Ahem... I realise I had made an embarrassing, some might say schoolboy error, in reaching my first review. In fairness, I did praise the quality of the acrylic, the precision of the measurements and cuts as well as the excellent packaging and delivery. What I described as a deal-breaker was that I ordered clear acrylic, but only after plastic welding the edges did I realise it was blue-tinted. I *thought* I had removed all protective films and double-checked for any obvious trace of a second 'skin', even picking at the edges with a knife, to no effect.
To the positive comments above, I can now also add that Cut My's customer focus post-sale is first class. I received a couple of messages after my review, politely checking on whether I was sure of the blue tints. Tanya: thank you. You were absolutely right and I feel like an ape-fingered buffoon. To alleviate my shame a wee bit, the final protective film is applied in such a way as to be indistinguishable from the perspex beneath. i.e. no bubbles, no peeling, uniform transparency etc. But it does yield if you persist, and thereafter it comes off pretty easily.
So, a word to the wise. Ensure all the film is off BEFORE applying plastic weld. And before writing a misguided review! Because this is an excellent product and, from what I have experienced, a really decent, efficient company. I'll certainly be back.
