So far so good. The sound is good and the design is cool. I haven't tested the water and weather resistant features but I will soon. If it fails the rating will change drastically since that is the main reason I made this purchase.

Dr. Wright presents his unique approach to curing digestive ills by actually eliminating the cause of them rather than treating the symptoms. The crux of this book is to identify whether or not you have weak stomach acid and then treat it. I don't really want to treat myself for low stomach acid without knowing if I actually have that condition what my baseline is to start. Note: if you are taking meds for indigestion Prilosec Nexium etc they work by lowering your stomach acid and will not get your true baseline reading just your post med reading.

I am on my second because I handled the other roughly and broke it. I did not hesitate to reorder because I use this all the time for podcasts, music and hands-free phone calls. This fits right into my ear and stays put without any additional support. Very reasonably priced. I am considering ordering spares to keep on hand in case this item for some ridiculous reason is discontinued. Highly recommended.
