Very pleased with the ease of use the only problem is its difficult to control the amount of sealant coming out of the tube in fact i had too much but then again nothing a scrapper couldnt fix easy to use and was good not to have to purchase the gun seperately to use the sealant as described easy to use ideal around showers i used masking tape and the easy flow control gave a good finish used it again about 3 weeks later on another project and still worked as well as the first time
