This is a very attractive and very well-made railing planter. The deep interior allows for plenty of room for soil and plant roots. The sturdy hanging brackets are easy to assemble (I needed only a 6-inch adjustable wrench to tighten cap-nuts.), and adjust to a wide range of railing widths. I needed to reverse part of the bracket to allow it to adjust to our narrow metal railing widths -- the instructions do not show that. Also, we added padding to the inside of the brackets and to the horizontal leveling bar to prevent scratching of our metal railings -- that won't be necessary for wooden railings. One additional note: Yes, there are drainage holes to allow excess water to escape but the bottom of the planter's interior is divided into three segments -- two have drainage holes, the center section does not. I used a hole saw to add the missing drainage.
