Thetford C200 Toilet Fresh Up Set with Toilet Cassette
Great product
Was slightly longer than my original but was able to cut down. A lot cheaper than one on a UK site, even with shipping. No issue at all with delivery to the UK. Infact, it was ordered after another related product I purchased in the UK and was received before the uk one! Also, excellent tracking each step of the way. Puts the UK delivery system to shame! Really pleased. Would order from again. Thank you.
Very happy with purchase of ladder for our van. Easy transaction and swift delivery. 🚚 works for us.
Nice product easy to install comes complete with all the extra bits to complete the job 👌
The tow ball scales work well. Takes the guess work out of knowing what the ball weight is.
