Can anyone speak about durability? What is the general lifespan of BioGrind sleep guard?

It has been very durable for me. I chose this one because it was more substantial than others. I don't have a time frame, but the one piece covers both upper and lower and holds up quite well. Hope this helps.

I must be going about a year, and no sign of deterioration. I feel like I should order another one, in case they stop making them. Seems like a really good product - save $800 (your dentist doesn't really need to replace his Porsche anytime soon).

I have the original Zrest and have used it for about 20 yrs. I backpacked and drop camp with the Boy Scouts for about 15 of those with 3 trips to Philmont Scout Ranch and some form of either backpacking or drop camping virtually every month. I still use it when staying at our son & daughter-in-law's. I am looking to replace it as it is not quite as resilient as it use to be, neither am I.

I highly recommend this one, we own 3 of them and they have been rock solid for us for about the last 3 years. http://www.newegg.com/Product/Product.aspx?Item=N82E16817392044&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Hard+Drive+Enclosures-_-N82E16817392044&gclid=CjwKEAjw56moBRD8_4-AgoOqhV4SJADWWVCcTrv06Ew4bvd9ASwWY7J922tvEgOMrHRcKMA6u91ixxoCMWfw_wcB&gclsrc=aw.ds

I've had mine almost 2 years now without any wear on it. I'm sure it depends on how rough you are with them, but my case has been great this whole time.

Well, I know that they last at least 36 hours on the highest setting. I haven't done any tri benchmark testing, but was doing some work using it and got called away. I didn't get back to it until a day and a half later when I realized I'd left it on! It was still going at functional level at that point.

I got mine in a 2for1 deal-- it might have been Groupon, I don't remember. The one I gave to my kids and it barely lasted 6 mos, but I'm pretty sure my son took it apart to "see how it worked"... however mine has worked great for almost 3 years now. In fact even my dentist was pleased, bought one herself and now recommends them (along with Sonic care) I basically got mine free, but I wouldn't have paid $99 for it reading all of the negative reviews. Apparently I got lucky, but I love mine. I get the replacement heads once a year, though. If you're the only one using it I can't see why you wold need replacement so often since you rotate using the three brushes. I got mine in a 2for1 deal-- it might have been Groupon, I don't remember.

I've had two that have last multiple years and that's why I decided to buy two more, however the two that I bought most recently lasted between 6 & 8 months. I'm hoping Actiontec will replace under the 1 year warranty.

Thanks for the tip - will check it out. We use it personally. The first Tempest lasted 12 years. I got tired of all the others' blades breaking and before you realize it, you are ingesting miniscule pieces of blade! Not so with the Tempest. Have had the replacement Tempest for almost 3 years now. They pulverize ice and frozen fruits without lumps. I don't care about the 2 year warranty based on having owned one for 12 years. Sure, for reassurance, a 5 year warranty would be great, but then they'd probably raise the price unnecessarily. Oh - and also, I experienced stuck chunks of fruit in the other brands' containers in the "corners". The Tempest Wave Action eliminates that problem. Thanks for the tip - will check it out.

I've had theme for about 3months and the durability is incredible. The cable loop is very well made and shows no signs of stress. And if you still worry you don't HAVE to use it, but I really wouldn't worry.

I recently got mine so haven't checked replacement. I went to the original company and found out it lasts 5,000 hours in this one. Here is the site: http://www.naturebright.com/faq and the number is 1-800-NBC-0231 and ask them.I also found it looks like most health insurance carriers reimburse for it with a doctor's prescription and it has the directions to do so on that site.I'll look into my literature and see if it says or how much it is.

3 years http://www.crucial.com/usa/en/company-warrantyBut SSD can last for very long time and memory blocks can do upto 100k program and erase cycles plus wear leveling and on the fly repairs. Basically they are assumed to last for 10 years of continuous use. Well you're not using it continuously so it should last so much longer.

I dont know the exact lifespan of these, but I will say I've used them very steadily since I bought them in December on pulse mode and for at least 5 parties without a single hiccup! *knock on wood* Theyre definitely built well!

I purchased these quite some time ago. In order to increase the longevity of the devices I periodically sand them and apply a thin layer of cedar oil. (I bought via Amazon) I do this periodically, and the devices have worked without problems. I've had no problem with durability.

As the others answered the biomrtric lock is not very good. I tried all fingers and both hands and it would not consistenly recognize any of the combinations. Sfam-On tech service figured that my fingerprints are too worn down at 70plus years. Swittched to an identical model safe with a combo lock. Works great.

My previous one (same model), lasted more than 10 years, and I did NOT take particularly good care of it. Here's an excerpt from my review:"2003 - early 2014: This Marathon 8AM-U1R lasted over 10 years and was still working when I replaced it (with the same model) in February 2014, mostly just for peace of mind!"

I had one last about 3 years and I'd say it had at most 40 hours on it. I have others that are still working, but at these prices, there should be absolutely no failures at all - no excuses!
