These are great. I only used one so far for my fiddle leaf fig, haven’t decided on which plant will go in the second one. 
Because they’re plastic, they’re manageable to move around.  I did, however, fill the bottom half with empty water bottles to take up some of the volume to help the weight and using avoid using so much soil. 
The only thing I see with this is that the drainage holes aren’t at the lowest point of the planter. For some reason, they’re raised in the center at least an inch where they then put the holes, leaving a trench for water to hang out. I forgot to drill additional proper holes, so I had to carefully lean the pot to get some of that trench water out. Will be doing that at a later date (carefully, without touching the plant on top).
I think it would be 5 stars for me if the holes were useful.
