Overall i think the Koh products are great. I use a variety of prducts every week when cleaning, including the spray mop, universal cleaner and cltohs, grout brush, loo blade, laundry liquid and dishwashing tablets. The spray mop could do with a re-design of the handle to make it stronger. After some time the handle on my first mop split, i ordered a second one which also split after only a few months. I have taped it up with duct tape and it still works, but its not ideal.
