when there is no more drag on the blade that's what is doing the sharpening

when there is no more drag on the blade you are sharpening. the groves that are cut into the rod get worn to the point they become smooth. im not sure if you can " sharpen the sharpener " or not it would be best if you would call one of the blade manufacturers and find out for sure . otherwise its time to replace it

When you sharpen your knives and they are still feeling blunt, not cutting your food properly. It lasts quite a while though before you have to replace.

Under normal home use (I keep eight knives very sharp routinely) I have used mine for over twenty years. It looks to be good for another twenty. Unless allowed to rust, or abused in some way, I'd say it will never need replacing.

I would think you could tell when your knives no longer cut properly. Also I don't need to use it that often, so I believe for me it will last quite a while.

I had to order a replacement once, and it was pretty easy, really. There was a little confusion on their part at first, but it was taken care of. Email the customer service first. Let them respond. You may need to email them more than once. They will warranty their product. They should send a replacement quickly. I can't remember if I mailed the old one back or not.

When the brush no longer preforms properly You should replace it. All depends on how well you take care of your stuff.

They should replace it free of charge if you only had it a month. Of course if you have had it a long time the probably will not. It is worth calling customer service and talking to them. They are nice.

I don't know. Just replaced and I don't know how long it will last either. But sure looks better than before.

You don't "replace" them. You take them out, vacuum them, and put them back in. That way, you don't keep shoving out money for replacement parts all the time.

I'm uncertain about a replacement. It might be less expensive to replace the entire unit. Although, if you go to the company website they may offer one.

Couple months, depending upon your dust levels in your house. I replace it when it starts to look gray from dust. You cna go pretty long just know that the longer you leave it, and the lighter it gets, the less efficient it becomes.

Depends on the faucet you have installed. Some faucets have a "filter life" indicator which tells you when to replace.

I haven't had to replace anything but I would imagine you would contact the manufacturer.

I have yet to replace mine. As long as you wash, dry & power them they should last quite a while.

Write to the company. Since it has only been two months they will probably replace it.
