Braun Clean & Renew Refills (2 Pack)

It is a good shaver my husband liked it better than any he has ever had before.

I use the Braun cleaning station daily after each shave. I normally get about 34 cleaning operations before the yellow low fluid level light comes on, and 7 cleans after that before the red empty light comes on. I have found that if I lift the back end of the station up about 1/2 inch (I slide a toothbrush under it) when the yellow light first comes on, the yellow light goes off and I can get about 13 more cleans before the yellow light comes on again. Then I get the usual 7 cleans after that before the red empty light come on. In this way I have been getting roughly 34+13+7 = 54 cleaning operations per cartridge.

To prevent too much shaving debris from collecting in the cartridge, I brush the cutter and the top of the shaver under the foil before cleaning. To prevent damage to the blades, I brush the cutter with strokes perpendicular to the long axis of the cutter block.

It's amazing just how much dirt these things collect. They don't last as long as I would've liked, but they really do the job.
So overall, this is a great deal.
I would definitely recommend this.

Braun Clean & Renew Refills (3 Pack)

Braun refill cleaners perform as advertied.
I am very pleased with the product.

Supposedly this keeps the blades clean and sharp. It sure seems to work. But after about 1-1.5 months, the fluid seems to stop working regardless of how many times you've used it to clean the razor.
So plan on buying more than a few of these. For certain it really cleans the razor and so far the blades are only about half as dull as they normally would be. So a big plus, but I really don't like having to buy all these accessories and you can't travel with these as they are flammable. I wonder how just plain alcohol would work instead as it'd be a lot cheaper. Just bring an empty container and fill it with alcohol?
I'd like it if these refills weren't flammable so I could take them on the plane and also if they were cheaper, and lasted longer than a month.
