LAMZIX Lens Holder Double Lens Changer lens changing carrier for Canon DSLR Camera.

Although the concept is great, it still doesn't meet my expectations. Initially, I thought I could use this to carry an extra lens while I shoot, but unfortunately, it was more difficult to detach my lens from this lens holder and switch it with the lens on my camera. Because of that, I ended up not using this product as often as I would have hoped. Now that's my own opinion on this product.From a more objective perspective, I give this lens a 4/5 review because it is sturdy, reliable, and is well built to hold a heavy lens. I've used this lens to carry multiple lenses and it has not failed on me. You'd just have to make sure you lock your lens in correctly, and to me, that could be where most of the struggle is. The clasps on the straps that holds the lens holder are also well built, so I'm not afraid to have this swing around with a lens attached (although that is never a good idea to begin with). It could be a good product if it meets your needs.

didn't use it much, the device has a good build, however a bit hard to screw the lens, in and out, when in a hurry.

Total garbage. I bought this for my wife for Christmas. She tried to use it last week for the first time while photographing a baseball game. It immediately fell apart the first time she tried to attach a lens to it. Springs popped out parts fell off... the whole thing just disintegrated. Shoddy. DO NOT BUY THIS PRODUCT!

Connection is a bit stiff, but I'd rather have that than a loose one.
