DIN Rail Mount for Arduino UNO/Mega (3-Pack)

Really wanted to like this product and buy it again because it really will help me organize a project where I am using many boards (why not one star). However, most of the mounts which came have a significant bow. The mounts with this issue can not use all of the screw holes with the boards because there is too much bend. I'm going to go ahead with this time sensitive project and keep using them just for this project mounted with fewer screws, but unless they fix this issue I can't recommend, nor will I buy again in the future.Edit: The more I think about it, no, this is a faulty product due to the warping. Changed to one star. I can't even resell them once I was done using them. Biggest waste of money for part of a project I am working on.

They were all flat, looks like they fixed the warp problem. All mounting hardware included. I will definitely purchase more.
