I bought a Clarke DG6000DVES 5kVA Diesel Generator after being impressed by its' 5* customer reviews on the website. (Though I was surprised by how few reviews there were, I should have been more suspicious.)
Mine is noisy, gives off black smoke at 3/4 load and uses a lot more fuel than stated.
My 2 star product review has not been posted, I've emailed them 4 times, still haven't had a reply. I feel duped.
