Flomasta Universal Filling Kit 5 Pcs is rated 4.9 out of 5 by 28.
Rated 5 out of 5 by from Simple and effective This is great for a one off or occasional use to pour chemicals into a radiator bung. There is no seal around the plastic screw on bottle top, so I found a small amount of chemical leaked out while pouring. But it is still better than the alternative of trying to use a filler and hose pipe etc. Great value and I would certainly recommend.

Rated 5 out of 5 by from The way forward Simple but Perfect. Like most other reviewers I tried using a funnel first then went to buy this and saved time and spillage.

Rated 3 out of 5 by from Needs longer hose A good idea in principle, but a longer hose is needed between the bit that screws into the radiator, and the bit that screws onto the bottle. I managed to snap the hose connection when trying to fix the bottle on. For future, I have cut the bottom off an old bottle, and put a longer hose on, so can use like a funnel - should be easier!

Rated 5 out of 5 by from Just the job. Perfect. I think this will last a good while too, always handy to have. Makes adding the chemicals a much cleaner job.

Rated 5 out of 5 by from Easy Top Up Easy to add central heating inhibitor etc. to system. Saves adding to expansion tank. Just turn off radiator valves on one rad, drain the equivalent quantity of water from rad, then remove blanking plug on top of rad. Screw bottle cap to additive, attach hose and then threaded radiator connector. Screw into removed blanking plug opening and refill radiator, then remove and refit blanking plug. (It's easier done than writing this!). Happy customer with protected system.Thanks.
