Top Printer
Model: SG1000
This printer is strictly a Sublimation printer. It is not for regular printing. Once it is set up, it works really great and provides good quality prints. The drawbacks are.... the ink cartridges are pretty expensive. And it is somewhat of a challenge getting it set up and ready to use. It will not work unless it is connecting directly through a 2.4ghz signal. If you can work through those challenges, it is a great printer.

Stay away
Model: SG1000
This company sucks, product sucks, customer service sucks i can’t say anything good about this brand at all. I went through 5 of these expensive paper weights in the last 3 years.

Biggest disappointment
Model: SG1000
If I could give negative stars I would. HORRIBLE HORRIBLE customer service. Printer just stopped working. Images always came out grainy. Now my $1500 printer is just a boat anchor. No recommendations of a printer shop to look at it. Just a big disappointment. Negative 5 stars for me.

Buy direct from Sawgrass, not Amazon
Model: 500N BNDL
I'm giving the review based on the printer, Best printer Ive ever had, easy to setup and use.
Ink for printer is expensive but worth it. Buy direct or another company besides Amazon when purchasing though, Amazon customer services wont help you with any issues.
