Be careful.... I ordered a product in stock. Didn't get after 6 weeks so I followed up and told it was the last one and it was faulty. Couldn't give eta so I cancelled and requested refund. Was told would be done 3-5days, still waiting 25 days later. They won't supply pH number to speak to...absolute shithouse. After reading reviews now obviously will need to report company.
Following my previous review, within the hour I was contacted by the director the business who offered sincere apologies about my experience. I am pleased to say that a credit was applied the same day as he spoke to me. He has restored my faith in this business and will try again when I find the right product.

Approximate cost: $250
