Driver Alert Sleep Warning Device - Set of 3

I like how loud it is , however I bought the package of 3and one doesn't work. I don't like that the other two only work if your head falls forward and not to the side

The electronics function fine for this item. However, there is no way to adjust the loop to stay in place. For safety this is a good idea, but I have yet to figure out how to get it to stay in place. Since I got a set of 3 separate devices I am going to give them away and see if someone can figure out how to get it to sit as would a pair of 'readers' or 'off the rack sunglasses' which you can bend a bit.

I didn't end up using these much, many false alarms and they tended to slip off my ears. Instead, i just stopped at every rest area I saw and took a ten minute walk. Worked like a charm.

Great safety product ... especially for long distance driving trips which we frequently do in our motor coach! I ordered 3 ... and gave two to friends who also motor coach! Incidentally, I had my unit alert me no less than 3 times from a return trip from Fla ... and coincidentally ... they all occurred within hours of completing lunch! Great price, quick delivery and great quality ... a winner for safety!

1) Piercing, very loud continuous alarm (i.e., inside, the alarm was heard throughout our two-story house!) until head-position is "just right".2) Batteries went dead early second day of use. Trying again days later, they're still dead.3) TINY on/off switch.I'd bought two of these: Gargage.Rick J., Charlotte

Lightweight and comfortable, works great, would highly recommend.
