I have had it for a year (the Makita hr2631ft12) and I use it exclusively as a chisel from mortar to concrete. It requires caution when working with concrete. I read the reviews for the Bosch equivalent, which stated that it is not suitable for concrete as it will burn out. The Bosch model has a power output of 3.7J, while the current Makita has 2.4J. A high-quality machine like this won't burn out easily unless it is defective.
It won't get the job done quickly in concrete. It requires patience and caution to prevent it from overheating. If someone uses it with the trigger fully pressed, giving it the full 2.4J, which is 100% of its power for an hour, it will eventually burn out. However, if it is used with care regarding its temperature and with patience, it gets the job done.
It also requires attention to lubricating the chisel. Regular lubrication with high-quality grease is necessary.
Other than that, it has a very good balance, is comfortable to hold, does not transmit vibrations, has durability, and you appreciate every euro you have spent on it. I think, based on what I have heard from others, that it is one of Makita's most successful models in its category. It has a higher price, but you won't regret it unless your expectations were different, but that's not the machine's fault.
The 2.4J is indeed real. I believe it is a tool that should be in the standard equipment of an amateur or professional.
Update: I have also added photos.
