I purchased this microscope to replace my Celestron 150X which was damaged at work. Basically, this Barska microscope will perform well as long as you use it within its limitations.
1- Contrary to the description on the Opticsplanet website, there is no way to vary the light output.
2- Set up can be a bit tricky if you have a laptop computer with a built-in camera. When I plugged this unit in, my laptop immediately brought up the video software (as it should). However, it defaulted to the built in camera, forcing me to hunt around various preferences to change the input. (This is not necessarily the microscope's fault... just be aware that you may have to do some tweaking.)
3- The USB cord is a bit stiff and it repeatedly will come out of the microscope. This requires a reboot of the video software after plugging the cable back in. (I ended up wrapping/holding the cable in the hand I was using to hold the microscope.)
4- The microscope will zoom to 300X... that translates into "a little vibration makes a BIG difference". Taking a good photo at 300X while holding it is almost impossible. If you want to examine something relatively flat (paper, leaves, insects, etc.) and can place the scope flat on a surface, you can come up with some really nice shots.
Summary- If Barska would have thought ahead an included a stand (like Celeston does with some of their models) and a more flexible USB cable this scope would be quite good.
I use my scope to document...
