This tool has the least power which is at 425.5 Watt primarily because it was designed to cater beginners or non-professionals preventing them from getting overwhelmed by a high-power machine. In this way, they won't burn their paint while using the tool.
The product is also designed as dual action/random-orbit for the very same reason - which is to allow a regular car owner to polish their car easily without having to acquire certain high-level skills.
It has 6-speed settings so they have several options to choose from depending on how much speed they can handle and what type of work they want to do.

A unique feature of this tool is its pre-installed counterweight. This feature allows you to have a balanced tool while polishing. This makes this tool easy to handle and will make your work less strenuous on your hand and arm.
It also has a removable 2-position side handle so you can use whichever hand you want to use. If you don't want to use the handle, you also have the option to remove it. This gives you better control in handling and maneuvering the machine.
However, unlike the other polishers, this machine does not have the "hook and loop" feature. The good news is that you can replace it with a hook and loop backing plate or velcro backing plate so that you can easily replace your pad.
It is great that the machine came with a pad, however, it easily rips off after a few hours of use. We recommend buying a more reliable pad so that you'll be able to continue with your work longer.

I find this product to be a bit outdated in comparison with the other polishers we've reviewed although it has all the basic qualities that we need from a good polisher which are: durable exterior, easy to reach the switch, speed control, and long thick cord. Since the price is low, you are getting what you paid for. Still, I consider the product to be simple and ergonomic, it is safe with low power, easy to operate, and effective especially to those people who are novices when it comes to car detailing. I appreciate the fact that the product includes a pad however it is disappointing that it easily rips off. Might as well remove it out of the box to avoid disappointment or include a much better pad in the box. Since the price is low, I don't really feel that the company should include a pad since buyers would rather use a more reliable pad. After further research, I found that this tool isn't only used by car owners like us but is also used at home by women to perform everyday household chores like cleaning the front yard or windows.
Buy or not buy: I highly recommend this machine to homeowners and car users. It is extremely simple to use, safe and specifically designed for beginners and non-professionals. It is a good tool to have at home because the machine can be used not only on cars but on anything else that needs polishing. If you are tired of polishing your car by hand, you can use this tool to let the machine polish your car similar to a hand-motion. The only difference is you are polishing your car conveniently at a faster rate saving your energy and time.
