You immediately notice that it's got a circular blade, or cutting wheel, rather than the long blade that reciprocating saws have. We've included it here for comparison - Amazon classify it as a reciprocating saw, although the rotary nature of the circular saw means it cuts faster because the teeth are in constant motion.
The Saw-Max handheld saw is designed to be small and easily handled when working in tight spaces. The design also gives you a good line of sight as you work and the various cutting wheels included in this kit allow you to make straight, plunge, and flush cuts. The Saw-Max can cut through wood, plastic, metal, tile, plastic, and laminates.
Dremel claim that "it’s one-third the size and weight of a typical circular power saw—making for convenient one-handed operation. The worm-drive gearing system provides greater power, optimal control, and extended tool life. The Saw-Max also features an optimized grip diameter and switch placement for additional user comfort."
People generally feel the saw is robust and fine for lighter materials such as wood or plastics - some aren't sure about cutting through metal, noting that the blades are prone to wearing down quickly.
Overall the consensus is that the saw is fine for lighter work and the design does assist the user in being able to see what they're doing - but for heavier work, a more robust, powerful reciprocating saw would be a better solution.
