### ⭐⭐⭐⭐ Works fine - no covers
*by K***Y on March 22, 2021*

These are standard units (I have used many) and they work just like all their peers. However, these are the first SSRs I've ever bought that didn't come with a clear plastic cover. Not a big deal, just something I took as a given when I bought them.
