| These refills do exactly what they are supposed to do, as you can read in the product description. I have found no noticeable difference by cleaning my shaver every other use instead of every time. I have owned it for almost a year now. This is a good way to get twice the life out of the refills. They also seem to last longer than the 30 uses stated. Also, these things are very easy to spill when installing. Be careful! Finally, I'd recommend stocking up on them if you like the shaver because with products like these, you never know when the manufacturer will stop production thus rendering the shaver obsolete. |
