Can't be beat
I own a small automotive business and was looking into upgrading one of my products from used heat sinks to extruded ones. I contacted a few firms and received estimates in the $15 - $20/piece range with minimums of 200 units and 5 week lead times. When I found heatsinkusa I ordered a lot of just 10 units on my first order, paid under $5 each and got them three days later! I honestly can't believe how they compare to the competition. Unless you need a pallet of heat sinks I'm pretty sure they can't be beat. It's now a month later and I just ordered 20 more. Thanks folks, you've got a customer as long as people keep buying parts from me and you still exist!!!!

Top Notch Product
I own a business and started purchasing these heatsinks for automobile TFI Relocations. These heatsinks are top notch! The factory heatsinks I was buying from the salvage yard was cast and very expensive. These are all machined to exact specs! This is a great product with excellent service!

Good heat sink for the money
We tested this heat sink using a 10 watt source mounted in the center of a 3" length. We expected a theta s-a of 2.5 and measured 2.7. 4 stars instead of 5 because this sink was slightly warped. Cut edges were slightly raised.
