The options on duration and product type were quite restricted and didn’t suit our needs perfectly, so I had to get the next best thing, which wasn’t ideal. I only continued as it was highly recommended and really wanted to try it, but others may not persevere the same! I was also quite annoyed that the litre bottle wasn’t available when I ordered. We are currently using a makeshift container at home. Didn’t order the 500ml one as it’s too small and I would’ve been refilling it every day.
