Out of the box, this scooter feels very sloppy with initial use -- not usable, in my opinion. The setup instructions DO tell you about adjusting slack out of the folding mechanism. But, that's only a start, as it turns out. My scooter had some slack in the steering head bearings. At least one other reviewer took his Razor to a bike shop to have the steering head tightened -- the necessary tool (a very thin wrench of correct size) is not one that most people would have. I was able to make a tool by welding together a few pieces of 1/8 inch flat bar. Finally, the handlebar ends are too loose in their central mount. I fixed this by putting a single thickness of stretched electrical tape around the bar ends, before inserting them into the central mount. This is only practical if you intend to leave the bars assembled, since the tape gets destroyed with additional fiddling.The welds on this thing are fantastic. If only the rest of the scooter were done so well! My rear fender is not in line with the wheel. I took a good look to see if a custom bend to the fender would improve it, but, that was not to be. The wheel does just clear the fender, so, I decided it would serve its purpose; it's probably within Razor's expected tolerance.The folding mechanism can never be adjusted perfectly. Even if you tighten it up completely (and give up fold-ability) there is slack. The slack comes from the fit of the hinge pin through its holes. After doing a total of 6 miles in 3 outings, I've got some wear where the slack-removal button contacts the frame (see photo). I know people say they've ridden their A5's for hundreds or even a thousand miles... but, it's hard to imagine this wear not becoming a problem.Then there's the cute kick stand. Well, it's not really a kick stand, since it's not practical to deploy with your foot -- there's not enough of it sticking out where most shoes could make proper contact with it. I modified mine (see photo). I drilled a hole through the main piece just big enough for a #6 stainless steel machine screw. I got a nylon spacer from the misc. parts drawer at Lowe's (which I cut a bit shorter), and finished off with a washer and self-locking nut. NOW, I have a kick stand. I later realized the kickstand is a bit too long, and doesn't sit flat (as shown in the photo), so, I took it back off, and put an appropriate angle on the bottom, with a grinder.The scooter does roll well, with the large wheels making even stretches of brick paving negotiable. I had been worried about the steering post extension, where it is held onto the fork tube by a single clamp (Razor uses double or triple clamps on its competition models) -- but, that has remained solid.You have to get used to the limited space on the foot deck. I found it best to put only half or 2/3 of a foot width on the deck, which leaves some room for the other foot, when you coast. Keeping a foot off-center like that may seem like it would be a problem, but, it's easily handled by overall balance and, probably by some leverage that one automatically applies to the handle bars.I'm adult, 140 pounds, using my scooter when exercising my dog. Fortunately, I got the scooter at a good sale price, which allowed me to consider it a fair deal.
