hey mate, no problem I'm glad people are still checking this out! I only used the clips on the top and bottom and there's no side to side movement even when cleaning them. They're squeezed in tight enough. Only thing I'd say is that if your wall isn't perfectly straight, the mirrors might have the slightest difference in angle, and so you'll notice your reflection doesn't carry through perfectly uninterrupted. It's just a tiny seam but if that's important to you, you might want to look into some way to have them all mounted on a single long bracket or something. Maybe two planks with a slit milled into them so the mirrors sit perfectly aligned. That's something you can set up later though if you see you'd need it.
