I have had one of my Gidget II tables for 20 years and the other one for about 8. One goes in the motorhome and one stays at home They can definitely be tweaked so everything is perfectly level. It takes a while, but is worth it in the end. Once you can lift your machine, check where it is off level then adjust the chain. It can be done in tiny steps with the screws. Bigger steps (which yours doesn’t; need) are done by moving the chain links. While it is heavier than a SewEzi, it is also sturdier which is why I have no concern about leaving mine up even when traveling in my rolling earthquake otherwise known as a motorhome. I do tie the table down and put the machine on the floor underneath the table though.
