One disadvantage I feel the little differentiating speed setting compared to other wireless Dremeln. Here are just high and low are offered. For very specific missions in special materials that may be too little. The versatility of other devices with its stepless speed voters is not reached here, also extends the power may not be required for work where high speeds are required. This does not want to offer the device, its target group is the "hardware hobbyists" are bound to find here everything you need. All others who deliberately seek a cordless version, I make a comparison with the Dremel Micro warmly. That's a little more expensive, but also much more powerful.
