I'm overall quite pleased with this pocket sized electronic microscope. It's a decent quality build that old and young children alike will enjoy. If you are scientifically inclined like me and love looking at microscopic things to satisfy your curiosity, you will love this!What I like: Great small form factor. Easy to setup and use. I initially got started without even reading the manual. Does a pretty good job at magnifying and seems to be at the resolution it states. You can view pics on the device or you can use it to view on your PC which is very cool.What I didn't like: Buttons could be a little easier to press and maybe in a better spot. You tend to move the device by trying to press the buttons, but with a little learning you will get it. Device has memory to store pictures, but you can only view on the device and can't send to a PC, so recommend you install an SD card that is formatted immediately so you can save more pics and then transfer them to a PC. Really cool device and quite happy with this purchase. No doubt I'll be finding interesting reasons to use this for many years to come.
