I'm impressed. If you took the guts out of a handheld digital camera and joined them with a handheld field microscope, you'd have this. They did a good job. The sound effect output doesnt appear to turn off, that's really my only complaint. The strap is really good even. LEDs are awesome and have 6 brightness modes, plus off for ambient/side/back lighting. With a USB C data cable you can use it like a webcam, just plug it in and go, capture with which ever application you prefer.

The image quality is very good for an inexpensive sensor. It captures still images and video at 1280x720. Magnification is excellent, and the field is super distortion-free oddly enough. Check out my test images. The brass wire mesh filter has had no lens correction applied to it. Unlike old microscopes, the entire field of view is usable. I loaded up ImageJ, a professional microscopy suite, and did some image processing with it, the quality of the camera is more than good enough to do simple analysis. With a little effort, you could actually learn to do some image processing with it's output. I show the results of this in the video and images.

At the same time, this thing is so intuitive and easy to use, I think your average 5+ year old can get it figured out. It's definitely rugged enough to drag around outside and throw in a toy box. There is a microSD card, mine came with a 32GB card. If you're worried about junior inhaling SDs or something, you could remove it and just not save images, or put a drop of glue over that card to lock it in place.

Turn it on before plugging into your PC for camera mode, or it will enter charging mode and present a USB storage device for the microSD card.

Buy two so you can let your kid play with one. ;)

* notes about images *
The targets are a US half dollar coin, a brass wire mesh filter, and a juvenile female spider approximately 1cm in body length. These images are straight out of the microscope with no post-processing.

The greyscale image is an extended depth of field frame stack using b-spline wavelets to extend the focal depth, it is NOT straight out of the microscope. Video demonstrates 12 frames aligned, cropped, and registered using SIFT processing algorithm. Gives you an idea of what focusing through the field looks like.
