Amazing delivery and well packed.
I bought these for my dad, who is very pleased with them. He's used this product before, so knew exactly what he wanted. They arrived in good condition and in good time too. He's a happy man!
Very happy I received 3 x 375g so I was a winner all round.
Caustic drain cleaner arrived as stated by seller. It arrived within postal time, also well packaged. Just using it now to unblock a drain. It's worked and I'm very happy. Thank you seller for a great product.
fast response, works really well
Arrived super fast and products are great. I have been using these products for many years and will continue to do so. Many thanks!
Good overall product, I used to clear blocked drainage pipes. Easy to use. Did what it said on the pack.
I look to this product for the removal of paint from some of my models and this product looked like the product to do this task; awaiting outcome.
I am happy with this product,you have to be careful with its use.I have used it before for cleaning basin and bath blockages and it works.
Wonderful service, arrived super quick, very good price, i will purchase more in the future. Very good quality goods easy to use.
