Tiltall Professional 3 Inch Smallest LCD Screen Loupe with Soft eye Cup and Screen Protection

I own two of these lcd loupes. They are perfect for my cameras. I particularly like the way they collapse. They don't take up a lot of space in the camera bag. However, one has to exercise care installing the little frame that holds the loupe to the camera. I would give this product a five star rating were it not for:1) You can't order replacement parts. I've tried.2) The product doesn't always have all of the components. My second viewer didn't have any adhesive strips. That said, the adhesive strips are not particularly strong. I glued the little frame that attaches to the camera with silicone sealer. It is a bit of a tedious process because the parts are so small. I used two layers of sealer. One to attach the frame and then another, thicker bead all around the outside edge of the frame. I allowed each layer to fully cure for two days. It was nearly five days before I could actually use my cameras, but the bond is rock solid! I now have no fear of anything breaking and find the loupe really helpful.

So nice to have one that focuses! And very compact!
