Do the instruction stink? No, not really. There are a number of bits to put together and they need to be square and tight. That does involve squaring up pieces, torqueing them down so they don't shift and later needing to back out some bolts to add in bits while still having torqued bolts to hold the trailer square. It's really no big deal and with the right tools (and a beautiful wife's extra set of hands) you can make quick work of it. Flat surface is recommended for assembly. Room to spread out is highly recommended. As noted, easy to assemble with the right tools. From the time you open the box, expect to spend about an hour assembling it with an extra set of hands, 90 minutes or more if it's just you. It is sturdy for its purpose, we use it to bring cut logs and debris up out of the woods on a modest ridgeline without issue. A great value when compared to pieces that are cheap plastic being sold for more money or 2 to 3 times the cost for metal at the big box shops. On a side note, we buy from Vevor frequently as it relates to things to maintain our property, usually directly from them. We've yet to be disappointed with a purchase, the only disappointment has been missing out on a great deal on an item we've needed for property projects.
