Utterly useless. Don't bother unless you have time to kill / life to waste. No phone number as they are still not taking calls due to Covid - in September 2022. I contacted them using their online form: it does not work, I had an error message saying it was undeliverable. My last resort was the ghastly "online chat" - I was no 1 in the queue but it took 10 minutes for "Vicki Said" to acknowledge me. All I wanted to know was the size of one of their parts as it is not included in the description. I gave them the stock number and waited, and waited, and waited... I gave up after 15 minutes.
