In my old remote unfortunately a few of the more commonly used buttons (eg Silent key) have started to react badly. Ie. You had to push much more strongly. So I borrowed this ordered as a spare. Now in this the contacts are probably still okay for the rubber of the keys is significantly stiffer than the original. Therefore, you have to press firmly zielmlich fortiori in all keys. I had thought at the beginning, I'd get used to it very quickly, but it remains even after weeks an unpleasant feeling of having to push so hard and deep the keys.
Conclusion: If you have a total loss when his old FB, or has lost, is this FB certainly not bad. Can replace a just a little worn FB - as in my case - be a little disappointing.
It works basically the same as the original (ie electronically is fully compatible) - only with stiffer keys.
