Last couple years I've really gotten into Festool, tools. I know there are people who don't like them or complain about the price, but for the most part, I think they are worth every penny. with collection comes all the systainers and where to put them. I had lots of room under my assembly table, so figured that would be a great place to put some systainers and these are perfect for that purpose.One thing I really like about these is that use grub screws to install them. Since they use grub screws you simply do 5mm shelf pin holes. Gave me a chance to use my LR-32 hole drilling system. Wow, once you figure it out, it's such an amazing system. Once I got going, I knocked out like 6 panels so quickly. Course the drawers come with a detailed instruction sheet, Festool professionalism as usual. Once the panel are done and installed, the drawers go in quick and easier. Such much better than the hassle that usually comes with standard drawer slides.Drawers slide so smooth and easily. I wish they extended a little more, but it's not the end of the world. Just make sure you have room above, to be able to open the systainer lids. Drawers are well made and look fantastic.Very happy, on my second set of 5, would recommend.
