I have purchased a six pack of these trainers in the past and all 6 have failed--that is the voice becomes blurred and the buttons malfunction. I see

My last one failed after quite a long time, it just wouldn't go on, I changed batteries, tried to open it, but just figured it wore out. I just bought another one. So I don't really know why they fail. Sorry.

I've had mine's for 2 years. The battery had to be replaced but never any other problems. There are ways to change the settings. Check to make sure all buttons are aligned properly. Hope this helps.

I only used it once or twice and it worked. Your question makes me wonder though!

I've used mine a few times with no problems. I have two trainers, both different brands, and I use the other one more, so this trainer doesn't get much use. Sorry I can't be more helpful.

Both types of machines, single and double button will go bad after less than six months usage. I have returned back/exchanged at least 5 so far, and definitely not a product I will recommend to anyone. The manufacturer makes slight changes to the model externally but the guts are still the same. I have a lot of spare parts front the ones I repaired. Battery life is also terrible. Invest in a spray bottle that works off human power and a Arm & Hammer shower cleaner 50% cheaper than the Scrubbing bubbles and it is 100% reliable. Save your receipts for returns and you will not regret.

We don't know what happened, but ours never worked well. The controls were very finicky and we were unable to use them for training our dogs. In out estimation, these collars were a total waste of money.

I purchased a second box of them. I had no trouble with the first box, but this last set I bought, I have only been able to use about half of them. I put a CD in to record on and it opens up my tray drawer and says please put in a new CD as if the one I inserted had already been recorded on. I wipe it clean and try again. Sometimes it works, and sometimes it don't.

I haven't with this product, but it's happened with several other toys when the batteries are dying... Maybe try new batteries?

Yes, it happens to me... The batteries drain so fast, however, I remember the first batteries keept showing low charge for a long time but it worked. I have used it to teach 1-week trainings and only one week is enough to drain most of the battery charge. I tried swaping the batteries, apparently it helps to make longer the batteries life...

My husband gets one or sometimes even two from his. Suggest a new battery, although sometimes it does fade. He got his wet one time and now just the voice part works. He IS the hit of his golf buddies tho!!

Not sure as I just purchased six of them a month ago and they are all still working. I would think that after several years of use they may, in fact, fail at some point. Sorry I couldn't help more.

They don't work as well as some I have had in the past but they last for a good while for those button batteries. Sometimes the "target" has to push the button a couple of times before they feel the shock, others get jolted right away.

I have received a batch of 6 that all had the same frequency. I was forced to use two of them and they sometimes get out of sequence....one off and the other on. It would take 15-20 tries to get them to match again or you had to "un-plug" on of them to get them matched again. Not a good idea with these dimmers.

I have had no problems at all with mine. Send back and ask to just exchange the ones not working. Good luck!

I haven't had any of mine go bad yet. I have had other lesser quality, cheaper, ones go bad but not these. However, who knows, perhaps the company has been slacking off lately and going cheaper and worse quality?

Same problem here. Remote worked great for about a year and a half, now a bunch of my buttons don't work - or when they do they repeat. I finally had to throw it away and am now researching for a replacement.

I thought it was just me! I got my pair in summer '07, and they failed less than a year later. I had them replaced via Shure, and now the replacements have failed again. I don't use them excessively - they just seem to wear out. Other than the high probability of failure, these headphones are awesome.

Same thing happened to me with the last 3! I bought. They are no longer the quality item they were when I bought my first one a couple years agi. Get your money back!

I'd suggest contacting the manufacturer directly to see if they will replace. Get a copy of your receipt from the past purchases and see if they can help with a replacement

5 out of the 6 I bought quit working. I recently replaced the batteries and that did not work. They are junk.
