        Just awesome. Pre-drilled is a great feature. I used for a single channel Alpha J (mono-block) along with top & bottom rails. Hard to find anything this size at a better value. Thanks DIYstore!

        I love heatsinks.

        After many projects where I scrounged for surplus heatsinks that were always less than adequate and too expensive, I decided to try these. Very nicely done. How can they ship it to me from Italy to Whidbey Island so quickly - amazing!

        Fast shipping and top packaging

        The heatsinks was shipped to med very promptly after making the order. The shipping costs were low, as they were shipped from Italy to me in Norway, - within Europe. The arrived and I was impressed by the thorough packaging. The sinks themselves had some marks in their finish, on the inside face of them, mostly from a bit less than perfect anodizing-job. On the outside/fins (the most important part), they are perfectly black and no marks in the finish. Very nice to have pre-drilled/tapped sinks for my f4 project :) … Even buying from China (e-bay) and drilling/tapping my-selv, would have been more expensive. Great product!
