Haven’t really had the time to really use it but each time I did, it worked great. Can’t beat it for the price.

Nice product

This Gunpla Micro Pneumatic Pencil Die Grinder works well and handles very nicely. I didn't know what to expect since this was my first pneumatic tool but I am impressed with the power to weight ratio and how well it spins up to do its job.The one, and major item, I didn't like about it is that this tool uses a lot of air. I had it hooked up to my small home air compressor and the compressor had to run full time to keep up. Although the webpage for this tool does specify the air pressure needed to run this tool, it should probably also state the compressor size needed to run it. My compressor can achieve 90 psi easily but my tank is a smaller tank used for airbrush tools and even after letting my tank get to 150psi, it would exhaust the supply after less than a minute or so. I can use this tool for smaller tasks like deburring or a little grinding but anything more extensive and I will not have the air supply needed to keep it going unless I want to listen to the compressor going on all the time.The tool is small and fits in my hand comfortably. It is easy to control and accepts all the normal Dremel bits so it can work interchangeably with my electric rotary tool but until I can get a larger air supply, it will be easier to just use the electric rotary since the whine of the electric motor is not as intrusive as the full racket of the compressor going on full-time.

works well

Perfect for porting heads.
