-Not helpful in my experience--Unpleasant taste-Numbs tongue and stings tastebuds-moistens only gums and underside of tongue-Actually dries out roof of mouth inner cheeks and tongue--The few moisturizing effects it has lasts only 20 minutes--Net results in mouth dryer than before use--Same feeling as when dentist uses suction hook Is handy to have an extra for when my son inevitably bends his current mic too many times and it starts to crackle. I have tried the bike at my gym and physical therapist and I was surprised at how much more comfortable this one is to sit on. I expect the straps to split under the pressure of the buckles. So you can say this device works in more than one way. Luxurious and plush. I have bought Dearforms for many years and these are cheap knock off?s. These do the trick! Calzano correttamamente e non bisogna "tirarsele dietro". Case itself holds up to 20-24 which I find to be true as I usually for 2-4 days without needing to charge the actual case.
