Review (2/5): Sub-adequate shaver.
The power of this shaver is terrible. Requires multiple passovers and often pricks a few hairs in the process. Battery life is not very good as well. Avoid shaver.
The only reason I am giving it two stars is because the price is close to what you would expect for replacement heads. Which is exactly what I ended up doing after one week. I took out the heads and placed it in my 4 year old shaver and its been great!
