Because it’s a real glass front on the tile, it’s much nicer and more “real” than most of the peel and stick tile out there. If you don’t want to hire someone or do grout yourself, this is a great alternative. 
You definitely need a tile cutter to cut the tile. We got ours for like 30 at Lowe’s. Keep in mind a manual tile cutter only cuts one long straight edge so you likely have to cobble together a couple of pieces around outlets, and you will see a small seam. If you want it to look flawless you will need fancier tools and may as well just do full tile instead of peel and stick. 
They have been on a few months and the stickiness level seems good. I had the same tile with a stainless steel front in my last place and it lasted the 6 years I was there. 
The blue is maybe a little brighter than the photos, but that worked well for us.
