Sure it has its quirks and might lack all the bells and whistles (that's why it's not $400) but from an engineering stand point, this is the Tesla of bike trailers in my opinion (meant as a compliment). Let me quickly rattle of some of the things I love about this trailer. The set up and break down, the only way to make it easier and quicker is to have a button and have a robot do it for you. Somebody did their homework and designed this trailer so that all the pieces assemble and work together like a well written song. The wheels snap in with the press of a button, the back rest gets held up by a bar that raies up and gets locked in place, the top cover gets velcroed in place, snap in the handlebars and you are off. The tinted plastic windows help block the sun and keep the inside from getting too hot. The floor where the kiddos place their feet is made of tough material snd even has a place where water could drain if they spill a drink or have wet shoes. The rear wheels have shock absorbers so the kids have a smooth ride. The brake works by locking the wheels with the press of a button while squeezing the brake lever. The receiver arm attaches to the bike very easily and uses a spring so you could lay your bike down and the trailer stays upright. When using as a jogger, you have the option to lock the front wheel or let it swivel. The flag is made of a tough plastic material and could prob survive a hurricane. The top cover provides wind, rain, and sun protection and you have the option of just covering the kids with a mesh on hot days. The back of the trailer has a cubby where I was able to pack everything needed for a picnic. These are my observations after using this product for only a few days so the longevity has not been tested yet. I will update if need be. I used it as a bike trailer twice and as a jogger once. Mind you, I had an issue with one of the tires as whoever assembled the wheel at the factory forgot to put in rim tape resulting in my tire going flat after our first ride (the tube was rubbing on the spoke screws). I put some tape around the inside of the rim and got a new tube and was good to go. Have no doubt the seller has already reimbursed me for any of these expenses and is willing to send out a new wheel. When deciding what to buy, I was slightly concerned about the weight of this trailer but this truly has not been an issue. The large size of the wheels make the trailer with two kids feel like you're pulling a feather. I had not ridden a bike in a year yet was able to make it up a 30 degree, 150 foot long hill with two 25 pound kids in the back while only breaking a few beads of sweat. In summary, I do not think you will be disappointed if you buy this stroller. Your kids will love it and you will love the freedom and enjoyment of riding or jogging on an open trail.

I Love this, my kids are 3 and 5, and we bought the Insteep one for $103, totally wasting money, that one it just horrible, kids are not comfortable, they can even site well, it's a flat bottom with just a thin fabric, and the back metal witch is supporting the whole thing always popping out everyday, we have to buy a new one after first week of using it.
If you kids are over age 2, and you are looking for a heavy duty one, this is the one, seriously, I'm very happy with this purchase.
I use this to take my two kids to school, and food shopping, they are 3 and 5, my kids are totally around 70-80 lbs, and I can put 30 lbs of food with no problem, this one they can site down and comfortably, you can use it as stroller or attach it with a bike. very very awesome, I love it so much, and it saved me a lot of headache as well. I've compared so many products on ebay and amazon, I finally decided to purchase this one, because of the price, the functionality, the size and quality, and I love it even more after I used almost a month.
The customer service team also very professional and very fast response to your problem.

This is the jogging stroller to buy if u have multiple kids .it goes over large bumps and messed up sides walks well and the shocks seem to work very well also. The adjustable handle is great for changing and positioning while running and for if ur short like me. I have been using it for almost 6 months and my kids love it . I have 3 kids and sometimes I drop down the seat backing and all 3 kids can ride comfortably(not while jogging .) we use anytime we go places that could involve a lot of walking . It's come apart easily and fits great in my crossover . My only complaint would be at a still it Is very hard to turn. The front wheel swivel is a little weird . Sometimes I have to go turn the wheel myself the get going straight after turning . But only when u aren't moving . I be used it as a vileness trailer as well and it works great , as expected .

We adore this trailer. Only complaint we have it two of the tires tubes needed to be replaced within less than 2 months. Besides that it is really great, I use it every day as a jogging stroller and have also used it as a bike trailer. My 4 year old is getting a little too tall for it now, his head hits the top of the canopy but he doesn't seem to mind. My kids are very tall for their ages. My 1 year old loves looking out the little side windows. I love that it has storage in the back to store our waters and any toys/snacks we need. I wish there was some kind of water bottle holder on it when you use it as a stroller, I will be sewing one to hold my water bottle, phone and any other things I need in reach for jogging.

Love this jogger/trailer for the price!!! Only inconvenience I would say is that it's wider than the average doorway so I have to take one wheel off to be able to fit through the door, other than that, it's great! Also wished there was a strap to go around the wrist for safety in case you trip and fall, and would like a cup holder or storage basket of some sort around the handle while using as a jogger. Folds down easily to fit in the back of my car. You have to take the handle and tires off, which is an inconvenience, but it's easy to do also. I use it almost daily as a jogger and love it! It fits the three year old and 11 month old twins.
