POSITIVES: nice grips, good looking, comfortable, and the lighter colored insert is rubber, not hard plastic like the standard grips.
NEGATIVES: no instructions, and they don't warn you that installation can cause tiny parts to fall out of your gun if you hold it wrong.
Another review claimed, "Pop off the old grip, and mount the new one. It's as easy as that." Not quite! Yes, I used the Beretta Neos tool to easily unscrew the old grip, then popped off the old grip (with the aid of a small knife). But as I was trying to insert the new grips into place, two tiny pieces fell off the left side of the pistol - the slide stop, and a tiny spring that held the slide stop in place! I managed to re-install the slide stop, but the spring would not go back in. These grips should come with instructions to warn you to ALWAYS HOLD THE PISTOL WITH THE LEFT SIDE FACING UP while removing the old grip and installing the new grip. If you hold it the other way, these 2 tiny pieces can fall out, and the spring is very difficult (impossible for me) to reinstall. Fortunately, the slide stop seems to work okay without the spring.
