Review on 🌟 U.S. Art Supply Lightmaster USB Powered 18.75" Diagonal Pro Artist Size (A4) 9"x12" LED Lightbox Board - Slim 3/8" Profile Light Box Pad with 5-Volt LED Lights, Including 110V AC Power Adapter and USB Adapter by Jennifer Roberts

This machine is great for transferring patterns onto fabric. Dimming isn't a big deal as the low-end light tends to flicker, but the high-end is great and the LEDs last forever so you don't have to buy bulbs. The device is also very thin and easy to store. Comes with two transparent mesh and circle pattern overlays. Plugs into a tiny USB port and comes with a full-size USB port and power adapter. The dimming function can be annoying. If you touch the operating area in the corner while working (I'm left-handed, that was a problem), turn it off or accidentally lower it. This doesn't happen to right-handed people.
