The item was as described and good quality. It was a little more expensive than I would have expected but in keeping with other, similar offers. I have one important complaint, the person who delivered the package “ threw” it over my fence, onto the lawn. It was delivered to my door, or put in my post box, through the pedestrian gate. Fortunately you packed it well, so it didn’t break. Maybe for this type of item it should be labelled fragile, although I doubt this deliverer would have cared.
Great Seller, have no hesitation in giving a recommendation, went out of his way to give me a great deal on this high-quality blade. Was unable to obtain this blade with a 15.88mm bore in Australia, The Item was well packed for its journey from China, and arrived in the time frame that the seller advised My thanks for making this a fantastic buying experience. Arrived 11/11/2025 Armistice Day
Adequate packaging, fast delivery by post (9 days to a rural location), exactly as described, reasonable value for money. Looking around, it seems these particular patch cables are fairly limited, so I was happy to pay the price for them - buying standard patch cords and plug adapters would probably cost more! Good communications and fast response from seller - I recommend them.
