Superior Encapsulated Pellets, 60 Seconds, 500 cfm, Package of 10

These worked great. A couple seconds with a lighter, then throw it in a shop-vac and inject the smoke into the sewer mainline. It's easy to smell and see any leaks in the pipes, and any vents that are jammed up.Pro tip: one at a time is plenty.

These smoke bombs don't burn as long as the candle style I usually buy but the price offsets that. They worked well enough in my smoke machine to diagnose several leaks in my customer's drain and vent system. They filled the entire line as evidenced by me finding leaks on both levels of the house on opposite ends

They produce a bunch of smoke with no unpleasant smell or irritation, but they cost too much for what it is. Certainly for routine use. I used in the attic to confirm my contractor didn't vent my attic. They applied a film under the metal roof and simply draped it over the peak instead of cutting through through it so air could move out.

I was able to smoke test an entire commercial building's sewer system fairly quickly. These produce a lot of smoke, and worked great for my purpose. I highly recommend this product.

With a massive shortage of smoke bombs, these are a life saver!

Tried these out cause Kansas City is sold out of the wick smoke bombs. These were ok but used a ton more than we usually do.

Put out a lot of smoke for a small pellet.

Plumber wanted almost $2,000 to find where the sewer smell came from. I purchased the Electris Smoke Blowerhttps://www.amazon.com/dp/B07LDDHS75?ref=ppx_yo2ov_dt_b_fed_asin_titleand these pellets and found the problem for about half of the cost. I am very pleased with this purchase.
