With so many different models available, I struggled to decide which to buy, but eventually went with the S3233/52. It feels well made and doesn't seem to have the same hair pulling problem that my old Remington shaver did. It's comfortable to use, gives a close shave and hasn't caused me any skin irritation.
The only downside I’ve noticed is that it can miss a few hairs, which didn't happen so much with my older shaver. This is becoming less of an issue the more I use it so I think it's just a case of getting used to a slightly different shaving technique, going over the area in different directions.
The pop up trimmer also works well. Sometimes these pop up attachments feel flimsy, like they could easily break off, but this feels pretty solid and made to last.
The shaver can't be used while it's plugged in, but the battery life is really good, advertised to last for 60 minutes of use per charge, which seems about right from my experience. A full charge takes around an hour. It has a 2-pin charge cable that plugs directly into the shaver rather than any kind of cradle for the shaver to sit in. You will need a separate 2 pin to UK 3 pin adapter to charge if you don't have a shaver socket in your bathroom.
It comes with a soft drawsting pouch, which might be useful for some people, though it wouldn't offer much protection so it feels a little pointless to me.
I bought the shaver when it was on offer for £49.99 which feels like a reasonable price. I've been using it for a few weeks now and overall I'm really pleased with the purchase.
