Will Wright’s take

Based on the specs and price

Solid choice

“A fast, cheap Klipper machine for tinkerers.”

500 mm/s on Klipper for $239 is a fun deal if you like tweaking. It has no Wi-Fi or camera, so it's more hands-on than the easy-mode printers. Beginners who just want it to work should look at the A1 instead.
