Pretty acceptable given the dimensions covering most of the device's camera. I have used it on my laptop, computer monitor and even for work. The key is to keep the screen CLEAN, fingerprints/smudges/dirt CLEAN to keep it running. I will not use it on my iPhone as I use the camera a lot and risk losing the case. Not worth the trouble. True, if the cover is somehow "dirty". Simple, wet your fingertip and wipe once. Wet, wipe. Don't rub it, or the sticky side won't stay sticky for long. A laptop's lid can be tricky if you're not disciplined enough to simply move the lid towards the screen (monitor) when using the camera instead of placing it on a table, and it can easily get dirty or worse, get lost. However I would invest in a metal rail for my laptop as I use the camera a lot which works much less with this type of cover. I love this product!
