I will never use these again. If you like to spend a bunch of time fixing punctures only to have to go back and do it again, this product is for you. This product is worse than useless.

This is a simple device that is designed to do only one thing - charge an iPhone.  Despite some negative reviews I bought one because it was a reasonable price (for an apple accessory) and it worked.  A couple months later I bought another one for my wife's car, however, after a few days it stopped working.

Being the curious type I cracked open the case and found the cause of the problem - a loose wire.  A quick resolder and voila...better than new.

So if you think you don't have the skills (or at least a friend to) fix it I would rate this ONE STAR
If you are handy, it's probably worth the price and 5 minute repair so I would rate this FIVE STARS

On average...THREE STARS

Look elsewere for a guide to help you rebuild. I guess this book would be useful if you are a racer or something, but not for the DIY engine tinker-er.

I took on this project myself. Wouldn't recommend it unless you are really handy. The instructions were pretty easy but the template only caused me frustration and extra holes. Make your own template and you'll be much happier. Also note that the template and instructions say nothing about the depth of where to drill your holes. Wasn't I frustrated after almost 2 hours to discover there is a big gap. It is not flush. Too irritated to deal with it tonight. At least I know what NOT to do with the other side.  And like the other review said, you'll not be short of colorful language while installing this. . .and some banged up knuckles while you're at it.

If you are tired of having to worry about screwing up your valve stems when airing up your tires this is the way to go.

The hex sockets are pretty much useless. Obviously you can't get into tight spaces (especially the one nearest the handle), even if you can there isn't enough grip to get tight turns. Everything else was okay, haven't used the chain repair tool yet (hopefully won't need to).

I finally used the SMART Repair kit. Got a hole puncture and air deflated with no nail intact. Deflated the whole tire and then used the slime found that slime leaked out from puncture. Filled air and rotated the tire. Slime slightly leaked but began to stay steady without the tire deflating. Decided to drive around a few blocks and the tire seemed to stay inflated. I removed the tire and position of the slime to the puncture and used the spare tire to prevent being stranded. I rotated the tire for at least two days and seemed the slime was working. Decided to put the tire back and drive around for at least 2 miles. Seemed to last. So the following day I drove to my parents which was 8 miles away. While getting ready to leave the tire was deflating and the slime was spewing. If this is designed to be usable for less than 10 miles, I guess this works. But if its designed to go for beyond 10 miles this is a waste of money I want a refund.....

Do you enjoy spending extra time fixing mistakes of bad products?  Do you enjoy huge, gaping blisters after only a few cuts?  Do you enjoy crying out to God, asking why bad things happen in the world?  If you answered yes to any of these questions, these are the scissors for you!  They barely cut, and when they do, it's jagged and uneven and, in the case of right-handed users, veers to the left.  As an added bonus, the packaging comes pre-ripped open, saving you the time of looking for another pair of scissors.  But, for the trouble, the joint is sticky and needs to be oiled.  And they're so dull that they don't cut precisely; they squish and then cut.

TL;DR: Awful.  Don't buy.  Even if you're new to leather and looking for a cheap starter pair, don't buy these.

Like a lot of the other reviews say, these patches are worthless. I both followed the instructions and watched a youtube video to make sure that I was doing all the steps correctly, I sanded down the spot where the puncture was before applying the patch, put it on the tire and inflated to the recommended PSI. Within 15 minutes heard a low expulsion of gas and the patch released all the air, and I hadn't even put the wheel back on my bike for fear of this exact thing happening. I patched it again with a second circle, but then realized that there was no way I would risk getting caught in the middle of my commute with a flat because of a useless patch. Waiting until tomorrow when my replacement inner tube comes in.

Tubeless ready is a joke. Would like air even if there are no punctures. There is a manufacturing defect in the bead or the sidewalls.

Pretty worthless really... just covers very basic repairs only.  Anything specific to a given year is not covered well at all...

Put this stuff in my inner tube and got puncture the next day.  Tube did not seal, and what's worse is that the sealant doesn't dry on the tube such that I cannot repair the tire the traditional way either (the "sealant" keeps spewing out and ruins the repair)

The puncture I have appears pretty small, so if it doesn't seal this hole I'm not sure what hole it will seal.

I bought this to do some vinyl repair to the inside of the car door.  The husky pup apparently was bored and put a few small puncture bites to the door lining.

I've had this about 4 months and have had to take it apart a number of times to fix it.  There are 5 screws holding it together.  4 on the front, in each corner, behind the grey "Go Groove," rubber mat and 1 behind the sticker on the back.  First problem was the right channel quit working.  If I pushed the cable around by where it went into the main body, I could usually get it working again.  Until one day, I couldn't.  There are 5 wires inside that actually do anything (L, R, Common, + and -).  Luckily for me, there was an extra one inside the strand that I think was supposed to go to an antenna but wasn't hooked up to anything.  I substituted this grey wire for the right channel and bingo, it worked again for a while.  Next up to break was the ability to charge the phone.  Not really a big deal around town but if you're on a long ride, the juice drains quick if you're using Pandora or GPS.  Yet again, I cracked it open and since I was out of spare wires, I had to rewire the part that goes out to the USB jack.  There are only 5 wires to do, but it's a b! tch to solder those little tiny contacts and in truth, just not how I wanted to spend my time.  For anyone needing to do this, I couldn't find any wire that had 5 strands like I needed and eventually I ended up cannibalizing an old USB mouse to get the cable I needed.  I gave myself a lot more wire than was originally provided hoping maybe a little less tension and 2 layers of shrink tubing around the ends might keep it from breaking.  Be careful taking the cover off the USB jack.  I broke mine and have a zip-tie holding it together.

The new version of this product, has substituted a hard mount at the bottom for the lose wire method which clearly was a good idea since it really doesn't work very well or for very long.  If you need an iPhone mount and like soldering projects, this is the one for you!

theres a few bugs you have to work out before you can plug and play, and the process takes around an additional 3 hours... but definitely worth it if you like to roast tires :) and get a one up

As in other reviews, this thing works, but you can only do 1-2 tires at a time, since it needs a cooldown break every 8 minutes and the fill is very slow. The construction is not very durable. It works best when placed on a towel or similar, to keep it from walking around. But it works, and at this price point, it's a perfectly acceptable product.

Save yourself the hassle and order the flat free front wheel at the same time if you choose to order this wheelbarrow.  (Without naming brands, look for  one like this:  Size 4.80/4.00-8" Flat Free Wheelbarrow Tire, 6" Centered Hub, 5/8" Ball Bearing, 15.5" Tire Diameter  ... )

The tire failed to hold air,  (Having been warned, I tested it before assembly) and after removing the inner tube I located the pin hole in the  tube.  After looking at  the cost of a new tube vs. patch kit, and considering the aggravation of replacing the tube...etc, getting a no-flat compatible tire instead  was a no-brainer.  (Have you noticed all the warning labels on these vinyl  "made in China" tires?  All have the same general theme: "Don't stand close or look at the tire while inflating"  "Only a professional should service this tire" )  So just get the replacement no-flat tire now, I paid way too much for the one I ended up getting  -- due to lack of patience.

After getting a new tire from the hardware store,  the wheel barrow was relatively easy to assemble, taking less than an hour, using a large flat head screwdriver and a pair of pliers.  Most of the bolts are non-slotted  round head carriage bolts and that had me worried that things wouldn't tighten up but they did okay.  Loc-tite is always an option is they fail over time.

The metal used in construction  is NOT particularly heavy gauge, I wouldn't be casually throwing in large rocks, or bricks, without expecting to do some serious damage to the bed, but it should be fine for hauling gravel, dirt,  and bark dust as well as shifting around other yard debris.

A quarter sized area of paint was missing from the handles, which may not bode well for the long term integrity of the paint job,. but that also could be due to the complete lack of packing material during shipping.  Not so much as a bit of bubble wrap.  Along with numerous small scratches there was also a golf ball size "pucker"  near the screw hole for the rear bracket, but by the way it was painted, it was most likely a manufacturing defect.
