The Hammerhead versions they sold at Costco 3 or 4 years back are WAY better quality than the CSPS versions.
Not better quality and very poor customer service from the people at Hammerhead.
I purchased the Hammerhead from Costco several years ago. About half of the drawers were rusting, after about 2 years, on the very back where they were welded. For the most part this rust was only visible if the drawer is removed. On some drawers the paint was bubbling up and if you scratched it off there was rust underneath.
Since the Hammerhead supposedly has a lifetime warranty I was not worried. Wrong thinking on my part. Hammerhead was willing to send me 3 new drawers but when I told them it was almost half that were rusting they would not honor their lifetime warrranty.
When I spoke to someone else higher up the food chain, they said that they would send me all the drawers I wanted but I would have to pay for shipping. They are in California and I'm in South Carolina and the shipping was quite expensive. I just told them forget it.
Since Costco guarantes everything they sell I just took it back to them. They gave me no trouble at all. The unit was at least 2 years old when I returned it.
They only sold the CSPS tool chest when I returned the Hammerhead so I just got one of thoses. I noticed the drawers in the back are made different too. They do not have a joint in the bottom of the rear of each drawer. I think that' a better design since there is less chance for them to rust.
I have been 100% satisfied with the CSPS chest and several months ago when I saw Costco was selling a 52" CSPS chest I bought one of those too.
I'm sure glad someone brought up the issue of the quality of Hammerhead tool chest since it has given me an opportunity to related my experience with it.
If you have a Hammerhead tool chest you may want to pull out a few drawers and look at the back of the drawers and see if your's are rusting.
