Also, the plastic joiners are too short, making it difficult to disassemble.
The push in fittings are touching when using the joiners - making it near impossible to get something thin enough, but sturdy enough, in the gap to disassemble the unit. I certainly didn't have anything readily on hand, nor the time or inclination to persevere with finding something suitable for disassembling it.
