As noted by others the instructions are very terse. Assembly however is very straight forward, had it together in about 45 minutes including the "figuring it out" factor. Of note, the seat post on my mountain bike is thicker than the trailer hitch was meant for and it was somewhat difficult to get both bolts started because of the length of the bolts too short by a couple millimeters. Had to omit the lock washer on one bolt to have enough thread to get the other bolt started. The trailer tongue clears the bike rack perfectly so I can keep the saddle bags on the bike in addition to the trailer.

Construction of all components is solid, it was well packaged, and the paint and finish is nice. Overall a very well thought out piece of equipment.

Aired the tires to 30 lbs last night to let them stretch out a little before pumping up to the full 36 lb psi. This a.m. the tires were at 20 lbs psi. May need some inner tube stop leak, will see.

Took it for first test run, couple of miles down the road with a small load and I hardly knew it was behind me. So far I'm REALLY liking this trailer. I plan on ham radio bike expeditions and fishing trips and this truly beats the heck out of stacked milk crates on the bike rack!

Just have to remember to swing a little wider around turns and be careful on narrow paths.

This will be my o-fish-all fishing and and ham radio field day main mode of transportation!

It works great. It is easy to use and comes with a quick release attachment. It is lightweight, follows well, and pulls fairly easy on the beach. It is on. The smaller side, but can hold more than you would think!

Tools are included with the package, but I didn't care for them. I just grabbed two adjustable wrenches to put it together. It's a fast build. Looks good.

This was pretty darned good, but the issue for me is I'm short and if you put it under your bike seat it has to be up at a certain height and I'm too short to reach the ground if the bike seat is up that high. Therefore, I could not really use it on my bike cruiser. But its very sturdy and I love everything about it otherwise, its just my balance isn't good enough to ride up that high and stop without my feet touching the ground. So, its not the product as much as the angle of the height that is not working for me.

Was a little hesitate on this purchase because I usually don't buy items off amazon this pricey & more of a DYI guy...but man is this thing AWESOME! When I was looking around I didn't like the typical dog carriers because the 'enclosure' idea due seemed like heat trouble & lack of view for my boy 'Hoops' was discouraged - rigging this up seemed like an alternative to those cons.

With a few additions after assembly the dream was achieved, now my 13yr old bud and I have cracked up a lot of people in the neighborhood. (especially when I turn on the rope lights tied along the trailer frame on at night hehe)

I've had the trailer for two months now so figured that was long enough to form a decent opinion.

The product itself:

- Putting together was mostly smooth, instructions could have been a little clearer but if you're comfortable with tools you'll be fine [hex bolt alert - go get the bit to speed things up]

- When securing the 'spring axles' for tires do not overexert! I did, snapped the clip, and impaled my hand with exposed end. But now I've got a cool hand scar so...yeah sure go for it! (kidding.)

- When you fasten attachment 'clip' to bike make sure the red button isn't pressed against the bottom of your seat, this can release the connection and leave the trailer behind.....not that I know what that's like or anything...

- Another note on attachment: How high your bike seat is will determine the slope in the trailer 'bed.' Since my cruiser bike is on the lower side, the bed leans forward - but with my travel bike it's level since the seat is higher (really just an aside for pet's comfort in travel haha)

- The 'weak point' of the assembly is the bottom nut that fastens the attachment arm to trailer body beneath the trailer bed. Go ahead and replace the bolt they give you with a longer thread, that's what I ended up having to do because I wore through the 'stock' one in about a month.

- As for driving, don't get overconfident from onlookers and bank too hard around a corner. The location of attachment arm presents the opportunity for trailer to flip and dump out items in such a situation...not that I know what that's like or anything...

Otherwise this is a great purchase! :) Just go ahead and get it if you have an remote interest haha
