It works great once it's assembled, but assembling it posed a bit of a challenge. A drill will make the process significantly faster and easier to input the screws, as some of them are quite long to put in by hand with an allen key. The only other confusing thing is double check which screws are which because they are combined in the packets. For example there are both long and short screws in one package and are labeled "EF", so make sure you look carefully at the directions to know which is which.
