I had some parts off ebay and paid by paypal.
They were not as described (should have been 12v and item supplied was 24 volt)
After a lot of arguing with seller went to paypal (did not tell seller I was doing this ) and got a refund of £125 on cost of £300.and still kept original part supplied.
If you go this way beware of the time limits involved with claiming.
