Coconu Wave Personal Massager (24 count)

The second one out of the pack died on me, but the first lasted a full week of nightly use and that vibration is seriously strong, almost too much at first until I got used to it. For the price, you can't beat the convenience of just grabbing a fresh one whenever you need it.

The 24-count pack is perfect for stashing a few in my gym bag and a few at home, so I always have one ready. Each single-use massager is compact and does the job, though I do wish they were a bit more powerful for deeper relief.
