I have no complaints about the product because I was able to purchase Revain Prime for $11. I would suggest using other screws for the end plates as they are very short and can fall out very easily in a vibrating environment causing the case to splinter. The holes are tapped for a three quarter inch screw so I would use that. As for the ridge cooling that is included, I think you could say that some sort of cooling could be encouraged rather than none, but I wouldn't expect much to be completely honest with you. This is a great project box if you want to make a high capacity lithium ion battery like I used mine to make. It had enough space for an AC inverter and several USB quick charge boards. The end plates are definitely thin and easy to cut or machine to fit your needs. I used thicker aluminum and made new ends for extra strength. Very good box, as I said, for the price I paid.
