Faulty cable - Good customer service
Slightly more expensive than the most basic and cheap alternatives but unfortunately had a faulty cable. Seemed to have visible corrosion or water damage on the metal test end and the cable does not work.Only required for very basic voltage readings and have used a spare pair of cables with no issue so there is no fault with the meter itself. Did not want to have to go through an RMA process for a £20 reader. There is no fault with the meter and I have another cable so I can still use it without issue.Customer service promptly responded to my review offering a refund/replacement and I opted for a partial refund with respect to the cable as the meter itself is fine.Gives me faith this was a rare problem from a good company.
