Query: decent shaver, easy to clean

I've been using this model for almost 2 years now. It isn't just one pass and done, but I've never had an electric that was. It gives a quick fairly clean shave. I like the fact that you can clean it by just popping off the top and holding it under the faucet. The built in battery holds a charge for 1 month of daily shaves. I haven't had to replace anything yet.
