Very powerful, easily cuts curves/circles. Great quality product, hard wearing, the trigger can be a bit tricky to use at first, it clicks into place instead of just twitching or squeezing. By far the easiest metal tool for cutting curves. The only downside is that these little nail/toenail bits get stuck everywhere, they can be very sharp and will stick to anything, we recommend getting a magnetic pickup tool or having a shop vacuum handy. Fits into tight spaces more easily than other metal cutting tools. Be sure to wear safety goggles, especially when cutting overhead! Like every tool, it has its place. Not suitable for straight cuts, but ideal for curves.
