Pros: Quiet
Fast
Works well
Close shave
Comfortable
Side trimmer
Wet and Dry operation
Can be rinsed out

Cons: Can't really think of one to be honest.

Other Thoughts: Replaced a competitor's product that did not work for me, was noisy and took a long time to shave me, did not work with long hair and was generally a disappointment. Decided to try this as it was on sale. Well it was a surprise to say the least. It was quick to charge, worked very well out of the box on a two day beard (I have a tough, heavy beard), it was quiet and fast. I have used it with shaving foam, in and out of the shower, dry and even with plain soap. It has consistently given me a closer shave than a blade, with no discomfort. Finally an electric razor I can live with.
Recommended.

Pros: I ordered the Norelco 1250x/40 and haven't been disappointed. It does just what is says it does. Close shave and is easy to operate. The battery lasts forever and I love the LED battery level indicators. It tells you when you need to change the blades or clean them out.

Cons: A little pricy. Doesn't do well on long rough facial hair.

Pros: Got a 1250X to replace a 10+ year old Norelco that would hold a charge for about a day. I've had the 1250 for over a week and love it! It gives a much better shave than my old razor and I love the 3D action of the heads. It really helps with faces like mine with more sharp features. The 3 way pivoting heads help get all the nooks and crannies.

Cons: None. The only mild con is the price, but so far I'd say it is worth the extra $s.

Pros: Razor function itself is very good.

Cons: Can only be recharged through charge stand; not directly through razor. This makes it hard to travel with. The trimmer is under powered and of very little use. Overall I would rather have my 2002 Braun which failed at an admirable 9 years. The newer Brauns have disappointed.

Pros: Close shave (for an electric). Stays charged for ever. (I haven't had to charge it yet.) Offers a great wet shave! Looks rad.

Cons: Nothing gets as close as a traditional razor. The trimmer is almost useless. Not a good dry shaver.

Other Thoughts: I'm new to using an electric (Hence my low tech knowledge rating). I actually cut myself with this razor during my first use. I guess I was pressing it down on my skin to hard.

Pros: Can be used wet and with shaving cream.
Light weight.
Very flexable heads.

Cons: Price

Other Thoughts: Using this with shaving cream gives a very close shave.
Love this product. Best one I've ever owned.

Pros: -Very close shave (almost as close as with say... a mach 3)
-Quiet
-Fast
-Great build quality

Cons: -Trimmer is a bit noisy when you enable it
-High initial cost

Other Thoughts: I switched over to this because I have to shave on a daily bases and cartridges will irritate my skin if I use them that much. This get's about as close as 5 hours after a Fusion or Quattro shave, but since you can shave without irritation you are able to shave multiple times per day if you want to. This does cost a lot at first (the 12xx series all use the same tech btw), but if you replace your cartridge in your current razor once a week, you'll end up paying about $175 per year, and these heads last for a year (recommended).

Before I bought this 1250X I had bought a 1050, but the difference between the shaves are night and day- most notably the 12xx heads destroy those 'against the skin' neck hairs on the first pass without any hits against my skin.
