I found these after a family member noted complaints from co-workers if he vaped even outside. Easy to order on 421 Store. Arrived promptly and worked great. He will order replacements as needed.

Better than Smoke Buddy
Been using Smoke Buddy for a couple of years. This device doesn't have the annoying caps on each end to deal with and it keeps track of how many puffs so you know when to get a new one. Eats all the smoke I blow into it.
