      Good product / lousy shipping

      Posted by Scott Eaton on 20th Jan 2018

      Took over a week to deliver a pair of 24" sinks roughly 40miles via USPS. Not the fault of HeatSinkUSA - their products and service are the best. Just don't use USPS.

      Nice thick base, passive cooling friendly and gives good spread between COBs. Great quality and service from HeatsinkUSA, as always. Thank you!

      Excellent Quality

      Was extremely pleased with this purchase. Needed 4 in order to use for an LED project for growing herbs, I'll share a link when assembled and final, used thermal pad (TIM) - the surface was in excellent shape, no re-surfacing required.

      Thank you and I've purchased a 12" as well for a similar project for Cucumbers and short duration vegetables which fruit. It will be awhile prior to having the project underway, but as soon as it is available. I'll post this link as well.

      Can't be beat

      Posted by Jason of McCully Racing Motors on 9th Jan 2014

      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!!!!
