Me.
It does what it is supposed to but the dust is hard to see. I never actually found any leaks with it.

Surprised and delighted
Excellent product. We were really disappointed when we found out the Borzin gun had been discontinued and purchased this item as a backup. It turns out my guys like it better because it works just as well and is easy to handle. The people at Meter Mall were very helpful and professional.

Works well, but can leave powder on nearby surfaces
Does the job, but at times it is messy, leaving residual on the ground and elsewhere. Fortunately, I use it very infrequently.
