Ordered 4 sticks of this RAM and had to send it back to CLL because 2 of the sticks were found to be faulty. CLL tested them and replaced the faulty sticks. The quality is not premium, that's why it's so cheap compared to branded RAM. However, it works and there's been no further problems after running the replacement RAM for 2-3 days. Great service and support from CCL, as always.
However, DPD couriers made a complete "dog's dinner" of delivery, sending the package to a depot 300 miles away and taking 5 extra days to reach my local depot, from where I had to collect it. This was on a next day delivery too!. No apology or explanation was offered. DPD employ rogues and cowboys that CCL would do best not to use for any deliveries (in my opinion and drawn from my [bad] experiences with them).
