We have been using this product for over 12mths, it is our third order and are extremely happy with it. We have always tried to use environmentally friendly products in our cassette toilets, and there is the added bonus of being septic friendly. The cleaning 4 in 1 product is great to use throughout the van too. The added bonus with Eco Traveller it is an Australian made and owned product line and the customer service is great too. Delivered from SA to Qld in about 3 days every time. We can't recommend it highly enough, and have to all our travelling friends and others on Facebook wondering what to use.
