A low cost CO2 starter for tinkerers who want acrylic and glass work on a budget and don’t mind hands on setup. Its small bed rules out signs.

3.6/5
The pick for engraving businesses that run all day and want an RF tube that needs no water and lasts for years. Shops that mostly cut thick stock get more for less from the 70 W glass version.

#7 in CO2Full review
A feature packed 55 W CO2 for crafters who want a camera and autofocus for less than an xTool P2S. The unclear warranty makes it a bigger gamble.
