The design process was a bit long and painful, some bugs not allowing to reproduce and modify designs from page to page, but globally worked well. Also frustrating that they wait for you to be done to tell you that there are errors (not enough space between each sticker on the page). Once you know that it's relatively easy to use.
The stickers are good quality, but the red was not like on my design, it was pale, closer to a pink-orange than an actual red.
In my case I'm still really happy with he stickers, I make hockey stick stickers for the players on the team I coach and they were super happy, but if it's like your company logo it might be disappointing if the colours don't match.
Overall it's a good product for the price, and if I needed the same kind of stickers made I would get it from here again.
