Did one set when our regular supplier was way behind, and they were pretty decent. Preferred a paige box over what they provided, and while the power supplies were ul listed, I didnt like the no name brand.
BUT since the access to the back side was a pain in the ass I put in my preferred power supplies in a paige box and still was cheaper than my usual; supplier. And they were like 10 days vs 4 weeks at the worst of the fludemic. Fit and finish of the letters was excellent though.
