My experience is limited but I have to agree. Yet others say the slot limits the material you can perf cut...or that it trashes the work in difficult spots. I use mostly Arlon 6100, Arlon 510, Arlon 220 & 221 And Arlon 3220 overlam.
Ima need to get up close to one of these things and give it a sniff.
I live in the Boondocks with a capitol B. ;-)
Stickers are my "Passion". I work for a big sign company that does XX million a year in sales. Most of what we do is vehicle wraps, interior decoration, and signage... But I got into the business because I like stickers. So I bought my own equipment... after lots of testing and playing with machines I could only dream of owning... I settled on the graphtec. I've played with 100k Flatbed cutters (Yes, they work nice!) Summas (Not often) A roland print and cut (Wouldnt even consider it) And like 5 diff versions of graphtecs. The graphtec can perf cut small enough that I wouldn't sell stickers that thin because they'd just rip. It can do nice detail.... and I havent found a material it cant cut. Diamond grade / really thick reflectives... Yeah, I hate those and I've never been able to properly do a print and cut on those even though graphtec releases videos of it.
But Reflective, holographic, metalic... Thick MX graphics, No issues at all.
NSFW Link - This link is NSFW. An Instagram model bought some stickers... these are 2" Tall. Its hard to tell because of the close up, but compare it to the cut lines on the table. If you need to perf cut smaller than that, I think material would be your issue before a machine is!

I've done a few thousand different designs, and never ran into an issue with the graphtec. I'm not saying Summas are bad... I havent played with one long enough to decide if theyre better or worst than Graphtec. I grew up in the whole Mac VS PC Thing too... I'm sure some people feel the same. Personally, I love new equipment... Graphtec may be better this year, summa next... who knows! But you cant go wrong with either, IMO.
