how often are you suppose to replace the nighthawk itself..

From the instructions it says the unit will stop functioning after 7 years from first installing batteries and it will have a warning that it is no longer detecting CO.

You need to replace battery maybe once a year. My last CO detector lasted about 10 years. I expect this unit to last 5 to 10 years. I like this unit because the warning is in a human voice instead of a sharp alarm.

10 years, according to the instructions, as of April 2014. The warranty is for 10 years as well.

None through amazon or maybe 30 days, dorman honors the lifetime warranty but you have to send the old one in for inspection and wait for a new one. You must keep the original receipt.

Varies depending on use (for instance, how often backlight is turned on) but I would say on average 3 years or so. Your local jeweler should be able to replace it.

I agree, need to replace all when one goes... Love the game! Batteries lasted approx. 8 hours... looking for reasonable priced ones ourselves...

I have not replaced my battery yet and I have had the night rider 650 for almost 18 months. I use it almost daily and love the light and rechargeable battery. I have dropped it multiple times and had a serious wreck in Jan of this year and seriously scraped a section of the plastic but it takes a licking and keeps on ticking. I am buying one for the wife.

I have been using mine everyday for well over a year, and I have not needed to replace anything on it. I have not looked to see if there are any replacement parts available, so I can't give you a good answer on that. All I know is that I love this thing! This is one gadget that works like it should, and that is coming from a mechanical design engineer.......

I don't think it would be economical to replace the blade as the squeegie is cheaper or as cheap as new blades. and no I don't think it can be replaced anyway. Unless you clean windows more than once every 2 months (how many people do that? lol) it's worth its cost.

Are you asking how often I personally use the one I purchased or are you asking how used is one that's being sold "used"?

For me it's about once a year. Remember that you can save money by just buying replacement crystals and unscrewing and refilling your original cartridge.

In the Instructions it says when to change, I think once a year under normal use.

Same here. Also keeps turning on laser, killing the battery. I reached out to Tagua but no support or response. I did do some research which led me to work a channel for the weapon. I removed and reholstered BG 380 several hundred times and now somewhat easier to remove.

You can write to gerber and they will replace the old one. I had to pay $10.00, but at least it was the right one.

Mine has been working for several years and just now needs replacement. DOES not need frequent replacement. I've got them in both bathrooms.

From previous experience I had to change mine every 12 months. The nice feature about these units is that you can change the batterywithout taking the unit down from the ceiling. The little pop open door on the face makes changing batteries a snap !

Yep, mine loses time, too. So, I contacted the company and they sent me a new circuit board and control panel. However, the installation seemed so involved that I haven't done it yet. I'm thinking about putting a nice magnet over it. Because, you know, aside from the clock issue, it seems to be a great range hood!
