  • High Value definitely Worth the Cost
Size Name: Single
My home repair guy told me about this product, and I was so glad he did. This beats the old insulation hands down. It was so good for the smaller areas because it doesn't overfill since it is minimally expensive. There are no more drafts around my windos.

  • Fabulous product
Size Name: Single
Everyone complains about the plastic nozzle, so buy Picowe tool and be satisfied. I used the this tool, OSI foam and OSI cleaner. My secret is to turn the brass adjustment knob until it is clear "in" (clockwise), then back it out a turn to get a small bead when you squeeze the trigger. I wet my window frame first before applying my bead. For clean out, swap the cleaner can for the foam can, squeeze the trigger, and watch it blow out the foam. Then take the little nozzle that came with the cleaner can and externally clean up the tool. Finally, squeeze the trigger of the tool again to relieve some penned up pressure. So slick. Enjoy! ... show more

  • Very messy. Use gloves. Lay plastic down.
Size Name: Single
Used to fill hole in wall. Large hole, needed a stiff surface to patch. This helps, just doesn't go where it's aimed, straw doesn't stay attached. Very messy. ;However, it did help put a more solid surface for patching.

  • Should make smaller cans for small jobs
Size Name: Single
I was not able to figure out how to reuse the straw. So while it worked as a component in my efforts to fix a golf ball sized hole in my siding (caused by a golf ball!), it was a big can that I could only really use once.
