Great product
As an amateur DIYer it's easy to get concerned about what to use for filling large voids or cavities in and around your home. This product takes the worry away given that it's easy to use and reuse! I've had similar products ad they tend to clog after one use. This doesn't down to a clever application nozzel design. Would definitely recommend.

I had a gap around my bathroom window, being able to use the product 6 times was a huge benefit 👍

Void filling
I do like the dispenser and how easy it is to apply the product .. and plenty of volume in that canister. Next job will be in Leeds at the daughters house to plug some openings and services
