Love that the boxes are removable and self water. The roots are watered from the bottom up. I did put a hole in one box because rain water from the end of our gutter accumulates tooucj rain in it. The other 4 boxes are fine as is.

I love the size of the box. There is not a down side to using these. They can be mounted and they also sit sturdily on my baister. The squirrels have jumped through and over the flowers with no damage. The water in the bottom gives weight so there is no rocking or or falling off.

Unfortunately, one corner was damaged, but I'm not going to whine about it. The plants have covered up the broken section of the top edge. Hung up easily and most importantly, DID NOT SAG with just the 2 brackets it came with. Pretty good.

I purchased 6 window boxes at the end of the summer. I keep my plants from summer over the winter in a sunny window. I followed the instructions that were in the box. So it's too early to tell how well they will work but as far as I can tell they are fine. The Plastic is thin. One was broken but they immediately replaced it. Another was discolored and they replaced that. They are half the cost of others so I would say you get what you pay for.

These are awesome. Got them for a beach house and this is the first year with them. I planted Geraniums (which are hardy flowers anyway) just to see how they would work because we are only there on the weekends and they did fabulous! Next year i'm going to try more delicate flowers and we'll see how they do.

Ordered 3 of these, came with no instructions for brackets. Going to go with my gut and hope for the best.Update: turned out to be very easy to install. Had one that was broken, fast, easy and hassle free replacement.

These Flower boxes are great. They are easy to install and look very nice compared to the cheap plastic you see at the big box stores. Plants stay watered for at lest 5 days in hot weather.
