My one complaint, as some others have already noted, is that if you want to make an infinite-run of daisy-chaining these across a wall, they don't always match up perfectly. But, considering it's clear acrylic, probably no one is going to notice anyway as long as you've leveled each segment correctly, and so it's only annoying to my inner OCD child.That being said, on to the good stuff ...My mother is an incredible cook, and I've been a long-time baker, so the kitchen is often over-stuffed with all the tools and materials of our respective trades/hobbies. If you can see from the third picture, I've marked a space beneath the cabinet in a blue rectangle. That's where all the poor spices used to live. It was a pain to see what was there, it was a pain to get out, it was a pain to clean up. In short, I directly blame it for the fact that I discovered I own 4 bottles of ground cloves and 3 bottles of thyme and various repetitions of other items that I had no idea I had before I thought I needed to buy more.So I needed something that would be relatively cheap, would allow me to store the spices somewhere that is easily accessible, and yet wouldn't contribute to yet more clutter on counter tops or walls. For various reasons, there was no way for me to stow this arrangement inside a cabinet or on cabinet doors. This was literally the only spot I could think of to put spice racks, and at 3 shelves for $20+, it was certainly one of the cheaper options possible without getting something that was too cheap to last.I was both pleasantly surprised and somewhat dismayed by the thickness of the acrylic - obviously, thicker is sturdier is better, but these shelves were also longer than the cabinet siding could accommodate and I do not own any handy-dandy power cutting tools. So, the night after I received the shelves, I loaded up Jack Ryan on Amazon and had at it with a hacksaw.Three episodes later, I finally had four shelves ready for mounting. (Not to knock on Jack Ryan, but I think I got more of an adrenaline rush thinking about how I'll finally have a lovely solution to my spice rack problem after all these years than from its mid-season episodes. Sorry Jack, I've had 3 years to build up to this moment while you've only had 120 minutes.)For obvious reasons, I didn't want to drill holes (not the least of which was I had spent quite a bit of time painting those cabinets myself). So following some other suggestions, I picked up several packets of Command damage-free hanging refill packs - I didn't bother with the hook solutions, I just got the refills and attached them directly to the shelves themselves. You can kind of see the 3 strips I put on in the second photo. Considering that they're rated at 3 lb, maybe the three I had put on is overkill, but hey, loaded in, they looked and felt solid so it was a win. And sure, you see the little tabs underneath them, but at least on the surfaces I was mounting them on, they weren't that obvious and if a friend notices then they become cool conversation pieces about your mad DIY skillz.I wasn't sure what the little strips of acrylic that came with the shelves were for till I read comments about how they could be glued in place to help with the things-falling-off-the-edge-of-flatland issue. At first I was like "what the heck why are these all murky and filmy >:( " when I realized that, unlike the acrylic shelving, these little pieces still had their protective films on. So after I peeled them off and used superglue to glue them in place, they looked almost as if they had just been molded that way in the first place. Hooray!Since I needed 4 shelves for the spices, I had 2 shelves (and 4 cut off pieces) left, so I went with some other reviewer suggestions and installed them in the bathroom. Sadly, when I cut off the ends of the spice shelves, I was a little too impatient and snapped them off once I had reached the bottom piece instead of sawing through them, which meant that the edges weren't perfectly even. I tried sanding them down, but once again, I don't think this could be feasibly done without several more seasons' worth of Jack Ryan if one doesn't own power tools, so I just tried to glue them together as best I could - which, apparently, fell just short of level, but whatever, at least that particular shelf is above eye-level and I can feast my attention on its prettier siblings below.So, in short, yes, you can (hack)saw through these with a little patience, a lot of shoulder exercise, and maybe some Jack Ryan or other action/suspense series/podcast of your choice. If you want to glue any pieces together, superglue should do just fine (just don't try to hang any dumbbells off of it). Command damage-free hanging strips work just fine (well, at least for the last 24 hours - maybe that won't be the case in 3 years, I'll let you know if anything changes if I still remember this review by then). All of my spice jars, even the widest ones, fit comfortably in the space between the shelf back and front lip. Thus, 5 stars (even if my inner OCD child is still pouting).
