Bought this as I suffer with pain in my wrists and hands and I recently purchased a drill brush set to make cleaning easier and wanted something small and lightweight to use them with, this is exactly what I was looking for!
I dont think it would be any good for drilling into stone or concrete but more for little jobs around the house and is a good little screwdriver. Used it to clean tiles, tighten screws and put a bed together and it's been fab.
Would definitely recommend this product for light jobs but would need something more powerful for stone and concrete.
I've given it 5 stars because its serving the purpose in what I bought it for which is mainly as a lightweight cleaning tool and a handy screwdriver.
