Excellent, compared to other cheaper offerings it's nice and clean. Pics 3 and 4 show another brand I tried, they were cheaper for some reason, filed a lot, and the inside corner has a sticky and uneven flood, it's almost exactly where the head of the screw wants to sit impossible to get to there to flatten them out so the screw can sit half flush. This is what you want to find on these clips, this seller in particular has a nice clean product, I bought 2 of these 25 lots and both are of the same quality, please note all holes are clean the other cheaper ones need one Bunch of files to clean/knock out the slots. I trimmed the outer springs on both sides, I checked them and they're in 90. Will buy again from this seller.
