Very beautiful machine. Buying in Brazil at this price is very good! It arrived in 3 days! I am very satisfied. Later, I will update the review when I can test it on something heavier! Thank you very much to the seller!
Customer –
It was not properly packaged, the bag it came in was torn, but it’s complete and in good condition! I will test it later!

Extremely powerful machine. The fact that it has a hybrid head helps use two types of tools. A suggestion would be to add a lock to be able to use the 1/4 with hexagonal bits, because when drilling, the bit can end up coming out when removing. Another suggestion is to have access to the technical sheet and/or a better manual. Overall, excellent cost-benefit. If anyone has the technical link, it would help.

Good key for the price, I did some tests and it’s working perfectly.
Customer –
It seems not bad but it doesn’t have the advertised power.
Customer –
This seems to be a nice little wrench. It feels sturdy enough, and well balanced in your hand with not too much. Weight. Should be handy for teardowns. Bonus points for the built-in 1/4-in hex drive which will support any number of driver bits. Also for being well protected in the shipping box, better than most. I only wish the slowest speed was a little slower for starting threads on assembly work, but i think it will be okay.
