Sublimate well at 300 degrees for 60 seconds; however, they are definitely Flimsy as compared to smaller spinners and for some reason they are putting 5 to a cello bag! Which means if you are making to resell, you will need to buy cello bags!! This is the first time I've experienced this in hundreds of wind spinners purchased for sublimation. This is a big deal to me because I can't find 10x10 cello bags (and I shouldn't have to) so now my bags will not be the accurate size for the spinner as all of my others are because I sell them!

Exceptional

Size: 22, Size: 22

Great quality and price. Monitors are exceptional. Would buy again without question. Screens are quite resilient, great picture. I bought three and use them in a multi Monitor setup for my work laptop, I needed something to view wireing diagrams and scan tool information qt the same time. If your a Service Technician looking for a multi Monitor set up would strongly recommend this Monitor.

Great product and great price

Size: 22

I think the negative thing I can highlight is the pixel dentist isn’t that high so it doesn’t look as crisp but this is a great budget option when you are in a hurry (like me) or simply need a screen that does its job. I use it for home office and it’s more than enough.

The monitor has been working great. The color & graphics are sharp. It is also responsive to the computer. I got it on sale so it was a great price & addition to my computer setup.
