I think I've owned my original sharpener for 5+ years. This is my 2nd replacement set. The instructions say that bars should be replaced every 3 years. I held out for the first replacement because of the instructions, but I should not have.
Get these as soon as you have trouble sharpening. Just installed a new set, and those knives are sharp!

I purchased the sharpening set many years ago when I was in the USA. Now that it needed replacing I purchased this via a proxy (there’s no option to ship to me) and everything was received quickly. Installation was easy and now my knives are sharp again!

Great products!!!!!

Replacement parts did not fit, but I to sent it back, and they substituted new replacement arms, and it works great
