This thing is a beast. Mainly use it for bathroom and tile demos. Install an 18" bit to relieve the user a bit. It's heavy but very durable. I would buy again tomorrow. Only complaint is the trigger is big and pocket so I accidentally turned it off.

PERFORMANCE: The Bosch 11321EVS demo hammer weighs only 13.7 lbs and delivers an excellent power-to-weight ratio of 6.1 ft lb of impact energy and a top speed of 2900 bpm
Renovation of 3 bathrooms and kitchen floor. On the first day of the renovation, I used a hammer and chisel to attempt to remove the tiles and concrete backing. The next day, I rented a $100-a-day, 22-pound demo hammer that ripped through the tiles and my body. Weighing around 15 pounds with the tile chisel attached, this is the perfect tool for the DIYer or professional. This is a very high quality tool that has already paid for itself in reduced demo time and costs.
Pros
Versatility: Hammer-only mode for chopping and tearing; Material Metal, Plastic
Typical Bosch tool, well made, ergonomic and with the right weight for its performance class. No problems with mortar spalling, tile splinters or broken concrete. The adjustable handle is comfortable and does a pretty good job of dampening vibrations. My only complaint is that the switch is too easy to press when operating the tool, especially if you have a dust bag and are working around a hose. After all, you don't come across it that often, but this flaw sets it apart from all the good…
Pros
OPTIMIZATION: Includes Bosch Auto Max speed controller that delivers maximum speed every time the tool is turned on and adjusts impact power to the application; Vario-Lock positioning ensures the optimal working angle for the best chisel position
