Very useful
Genuinely surprised how well it works. I’m a diag tech at my shop and each plug seals almost perfectly. Makes looking for an intake/vacuum leak very easy when using a smoke tester.

Very nice addition to any smoke machine.
A must have for any smoke machine you decide to use. Well-built materials. I love the way it's able to stack up for storage. The only thing I would change is making the largest cone a little larger but so far it has worked on everything I have worked on so far.
