Cox Powerflow Caulking Gun 400ml is rated 4.7 out of 5 by 13.
Rated 5 out of 5 by from Solid I had been struggling with a flimsy sealant gun, which was making my hand sore. This sealant gun was a joy to use.

Rated 5 out of 5 by from This gun will spoil you for other guns! Solid, smooth and controlled in operation make this gun, IMHO, a cut above the regular offerings. Quicker and easier to use compared to my battery caulking gun for smaller jobs, making it my first choice for most tasks from now on.

Rated 5 out of 5 by from Smooth and fast action applicator gun Bought this a few weeks ago as was sick of several old cheap guns that were slow and kept jamming. This one works a treat!

Rated 5 out of 5 by from Great gun Was a bit sceptical about paying 3 x for a standard mastic gun, however after snapping multiple guns thought I would upgrade and it is a case of you pay for what you get. This is really well made , no flexing of the tube and has the strength to push thick materials through. It also has a lot more bead control and leverage so you don't end up with a sore hand... Worth spend a bit more.

Rated 1 out of 5 by from Not what I hoped for! Finally decided to buy a more substantial gun following many cheaper versions that broke when there was no where to buy a new one! This seemed well made and initially worked well then a tube of grab adhesive split inside the casing! After some time cleaning it out including using a small spike in all the crevices. Another different make grab tube was set up, a little adhesive on the wall and the rest inside the gun! Another time cleaning and yet another tube of grab adhesive and lo and behold more adhesive in the gun - enough time wasted so back to Toolstation for a refund and then back to my cheap gun!! Perhaps I was unlucky but 3 tubes and never happened before.

Rated 5 out of 5 by from Mastic/Caulking gun Great quality gun worth spending a bit more money than the cheaper ones for a more controlled finish.
