This base is very well made, sturdy, easy to put together, I own several and will buy more. A few nit picks though, and they are not insignificant. First the packaging is truly awful, I am sure when shipped by the pallet full to a retail location it's fine, but I've bought 3 of these and all came from different vendors all shipped with different carriers and all arrived busting out of the seams. The last one looked like it had been dragged here and it was the only one boxed in another box, the first two were just coated in a roll and a half of packing tape. Add to that the box is heavy, full of metal that is shifting around and has a nice glossy finish with pictures on it that is difficult to get a grip on. It's a box of heavy metal wrapped up like a coffee maker, doesn't really work, and the necessary tape cocoon doesn't help, it really needs to be packaged in a tougher (brown) multi-wall box which would probably cost about the same as the photo intensive box it comes in. Second, I'm not sure who came up with the standard dimensions, there are various "kits" to make it bigger, even crazy big if you wanted to, but the minimum dimensions are quite large for typical shop tools. The base comes with 2 longer and 2 shorter rails and those 2 longer rails are too long to snugly fit a full size cabinet saw, or a heavy duty shaper, or large floor standing belt/disk sander, or a large drill press, or a typical iron frame band saw on an enclosed base, all things very typical in a home shop, and based on the a fore mentioned photo packaging, this is certainly the market this was intended for. I have had to chop the rails on everything I've put this under, and the holes are drilled such that doing so puts you at the end of the pre-drilled holes, for any of the above applications, and even to get there you need to cut both ends of the rails to have enough pre-drilled holes left and they are formed holes so you'd need to drill and tap, and since the factory holes are distortion punched it's really not something you can reproduce and get the same thread engagement. Personally I think if it was packaged with 2 sets of the shorter rails and the longer ones were available as a reasonable cost option it would be a better product, or there were more pre-drilled holes on the inner rails, like all the way across instead of just a few on either end. I'm just not sure what particular product they had in mind when they came up with the dimensions they even sell an outrigger for this for extension tables for, which can be purchased as a kit with this base, which you'd think would be intended for a Delta Unisaw, or a Powermatic 66 or a Sawstop Professional, or any one of the off shore clones of such, or one of the many hybrid saws, but these all have about the same base dimensions, dimensions smaller than this base can adjust to. Speaking of the outrigger, which I also have, it is also weirdly oversize, it's 32" front to back and none of the saws mentioned above have tables that deep and certainly not a leg support needing those dimensions. Even the Saw stop industrial is only 30" deep with a support leg footprint significantly smaller than that. And this cannot really be cut down in any sort of reasonable way as the castor supports are welded onto the ends, so somewhere you end up with a trip hazard. And the bracketry for the outrigger is also odd, it has some strange clamp dealy on one end that clamps around the inner crossbar of the main base and a flanged end that bolts to that oversize table leg support, which by the way has holes that have no relationship to the hole spacing on the bars of the main base. The whole thing could be simpler if they just drilled the holes all the way across on the main base and used the same spacing on the outrigger and just gave you 2 of the same bracket. it would solve multiple problems. Interestingly though, the outrigger does not share the same picturesque boxing of the base, and is well packaged, not slippery and arrived in perfect shape. But anyway, it is a good, solid product, which I would absolutely recommend and was a huge step up from the Delta mobile base I had on my Unisaw which sagged in the middle at it's only lift point and became not very mobile. Having 4 rotating casters makes it a breeze to move around, it locks down solid, is easy to level, can effortlessly operate it with your feet, it just seems to have a little too much marketing in the packaging, and a little too much counter productive generosity in it's dimension. I really do wish they'd made it less generous and upsold me kits to make it expandable in steps, for both products. All in all it's a well built product, but I can't say it's a particularly well engineered product at least not from a versatility stand point. There are recommendations in the Q&A to solve the size problem by putting in a plywood base and then putting whatever tool you have on that, but this just seems like a bit of a cheesy hack to a problem that shouldn't be there in the first place. Especially considering this product is coming from a company that makes a base based on your supplied piece of plywood, and if you really wanted to stick your machinery on plywood would you have bought a "Super Duty", rated to 3/4 of a ton steel base? So, Bora if you read these, either A) drill more holes in the rails, or B) make it smaller and sell me stuff to make it bigger, or sell me stuff to make it smaller, either way. Oh and just make the hole patterns the same everywhere and you'll need to make fewer unique parts, then even the extra up sell parts are just the same really, you could be selling me all kinds of different size rails that are just cut from the same continuous hole blank, and lastly get better (and cheaper) boxes and put a label on it if you want a picture for the sales floor.
