Here's a blast from the past. Can't remember exactly when I bought the square zap from Rick but I would guess around 25 years ago. She still heats up. Picked up the little bubbler from him too. My most used glass piece by a large margin. It's never left my log vape table.

The last picture has my Woodscents which is around 8 years old. It's been plugged in 24/7 since I bought it. I've mailed it to Ed once for a heater upgrade then again in 2020 for repair. Each time ended up getting a new woodshell. He recommended this wood instead of the original Walnut.

I've basically had a log vape running 24/7 in my home for the last 25 years. Person gets spoiled by that on-demand heat.
