Review (3/5): Good for a quick, mostly-okay shave. Has difficulty when it's hot/humid.
I grew up using electric shavers, and until recently had never ever used a multi-blade razor.
I've used this shaver at least 3 times a week for about 2 years. During that time I needed to change shaving heads twice (which seems fairly normal to me).
Things I liked about this razor are that it holds a charge for a reasonably long time, it does a decent job, and it lasted me a fairly long time. I feel like I got my money's worth.
What I didn't like about it was that the blades had a really tough time snagging hairs when it's warm or humid. You definitely need to make sure that your face is very dry when using it, or else you'll find yourself pressing it against your skin to try to pick up a stray hair that it missed.
The other thing I would mention is that it had a habit (especially toward the end of its life) of yanking on hair or two when I shaved with fairly thick stubble. Nothing too awful, but a surprising jolt now and then.
Overall it does a reasonable job in a pinch, and for a long time I never really knew what a good, close shave felt like so I was always content with what I got out of this shaver. For something that you will be using several times a week, I would put down a few extra $$ and get a nicer model.
