Familiarity: I've used it once or twice and have initial impressions
The mounting system is thorough and works well enough. There is an impressive amount of storage space as well. You certainly can't beat the price for this one.
The only complaint is that it seems to lack a bit of structural integrity, so if you load it up, it sags a bit.
