I'm happy with these. The only downside seems to be the supplied screws - a colleague told me to go to the hardware store and get stainless steel screws to use instead of the supplied screws. That has turned out to be a good suggestion. But there were 4 screws in the product as delivered, the screws that hold the 5/8" top to the top plate of the box. And, lo and behold, three of those 4 screws are already stripped on my 16" box, which is the one I use the most. Titan is great about warranty things - they've already sent me a replacement 16" box which I havent' assembled yet, but when I do, I'll be removing those 4 screws and replacing them with stainless steel screws.
