I love Swift microscopes but I've bought this product twice now and it doesn't work at all. The part that is held in the phone is even wrongly constructed. The tiny screw on top that tightens the hardware around the eyepiece doesn't even do anything. I have a Swift 350B microscope and according to the description it should fit and work, but it doesn't work. It seems like a great product, they just need to use a better mechanism to tighten it around the eyepieces and not fail so often due to other defects.
