“These are pretty good quality and are really good value for a set of four with the included organiser.
The dividers are a decent fit for anything other than the smallest items (for example some very thin washers will eventually work their way past). The sections are a good size for the kind of stuff you'd keep in a tray of this size, although with the corners not being rounded it can be fiddly to get the last few bits out if the items are small.
I have three sets now and they stack up well - they do take up quite a bit of space, but I can pack so much in and I'm finding them very useful.”
