MeterMall S220-KIT-B Regin Smoke Pen with 6 Wicks, Regin S221 Refill Wicks (6) and Carry Case. Dense, White Smoke Trail for Finding drafts and air leaks.

and from my professional opinion, I like a lot, only inconvenience I found , you should make it all metal no plastics to make it more appeal to HVAC technicians, we look always for well done tools , not chip imitations, if you know what I meant. not that your is bad , just thinking loud. I love American made tools. and we are loosing that pride with plastic tools.

It is a good product, so far. I only have an week or 2, but product it self is a winner. Just thru the Amazon, there is s & h fee almost high as the merchandise. Besides that works find I can see the draft intake and outtake around the air duct and doors and windows etc.

As a home inspector I look for tools that will make my job easier.This just happens to be one of those tools.I was quickly able to check the water heater for back drafting.I was also able to check around the doors and windows for air leakage.Now with all that said I still think the price is a little high.Even with that it is still a five star product hands down.

I like it ,it’s a great tool to have for checking drafts

These smoke pencils work much better than the electric ones available. I use mine on a regular basis in building air flow evaluations.

Simple but the instructions use aren’t clear. Get a good ligther.

Great product, did exactly what I wanted. Quick and easy safe smoke generator for finding drafts in house.
