As someone who isn't in proud possession of fine bathroom sealant, I find this powercaulk sealant gun very attractive in a 'coo, tools, must get and wield' way. Especially as its makers Black & Decker say even a novice can do a professional job with this gun. It has a consistent flow of caulk, a non drip tip and two speeds of application. Powered by four AA batteries - £29.99
