I bought 1x 4GB RAM to test it out in my QNAP NAS (seeking to increase its RAM but unsure about mixing brands) - it worked fine so I bought another. I now have 8GB RAM and the QNAP seems happy => I'm happy, too :)

Excellent service. Fast delivery, good packing, I recommend this seller

Perfect. Needed more memory for working from home. Just the job.

Excellent stuff. After adding this ram, my pc performs much better. Highly recommend.
