The description on the sander from the manufacturing company states 380W and not 700W. It is only eccentric without reciprocating motion.

Very good for amateur use. Good quality/price ratio. Tested on car headlights with a polishing compound and it looks like new. The speed selection is also very helpful. Overall, I am satisfied.

For the price, it's good. The sponge that comes in the package breaks after 2-3 uses, but with a good larger sponge, it does a satisfactory job. It takes minimal effort to produce smoke and I don't know how long it can withstand usage. It is for small surfaces. The vertical support is convenient

For amateur use only. Suitable only for polishing small surfaces. It heats up immediately and if you press it, the speed drops almost to zero. The 700W is probably a joke, its power should not exceed 300W.
Among the positives are its very low price, its very light weight, and its ergonomic design.

I have already used it twice, for its price it seems very decent although it heats up quite a bit, hence the 4 stars. The performance will show, otherwise it has the ability to use a larger sponge, the speed controller is not perfect but it does its job... It is lightweight and the handle it has is quite convenient since due to the temperature it emits, you cannot work with it otherwise. If you push it too hard, the speed decreases, it's okay, it's 700w and not professional. I will write it again, for 40 Euros it is very decent.
