Super heavy duty, no issues
This is a strong plug, heavy duty, over built, and I doubt will ever have issues.

Hots are not bridged
I can’t ding many stars as this works just not my application. If you are adapting a 120v one phase generator to a 120v one phase generator transfer switch only half of your circuits will power up. Look specifically in the specs for bridged hots. Hopefully saved some headaches. I’m grateful for the circuits I did have after Hurricane Beryl and the power out in Houston. I’ve since corrected my mistake.

Works!
It works to adapt my dryer outlet to locking L14-30. However, the locking L14-30 was a bit tight of a fit and looks like some plastic came off. No complaints otherwise tho, using this with their Y-Splitter for L14-30 too!
