I REALLY don't think anyone tested these skates before production.

I was not expecting awesome skates by any means, however these just don't even technically work.  You might be content with your little one walking in skates, but I'm not. The wheel lock feature allows you to control wheel movement - Level 1 for fixed wheels and Level 2 for wheels that only roll forward and not back.  Level 3 is supposed to be for free rolling wheels and real roller skating.  Well, unfortunately this adjustable wheel lock system does not stay put on the setting you select and unexpectedly changes itself.  Immediately.  Constantly.  I've resorted to trying to duck tape it in place.  I'm a roller derby skater and have skated since I was 3, and my 4 year old wants to skate too.  The only reason we still get this type of plastic adjustable skate is that his feet are still just way too small for regular skates.  This is his second pair of plastic adjustable skates, as we were replacing an ancient par of Spiderman skates because we wore out the buckle.  I was hoping with these he could really go for it.  But not really.  Oh well.  And it sure would be nice if little kids' skates had actual functioning toe stops.  Hard plastic doesn't work.  These skates are also rather wide at the wheel base, forcing a weird stance for little legs and hips.

I bought these skates for Roller Derby because they said Roller Derby, that was stupid. They are NOT good for any kind of sport. If you just go to the rink occasionally and want your own skates they would be fine, but if you want something substantial then spend more money.

I just purchased a set of 8 replacement wheels for my inline skates.  I installed new bearings and spacers in the wheels, then mounted them in the frames of the skates.  It seems that 3 of 8 wheels had torsional play, which is something I have never seen before.  I double checked that the axles were properly tightened.  They were.  After further investigation, I found that that the recess in the wheel to hold the bearing was too big, and is causing the torsional play.  As in the bearings should have a very snug fit in the recess, these, fell right in.  I will have to see if they are willing to replace the wheels.

Bearings do not align properly with floating spacers maybe it would work better on 6mm spacers. if you have speed skates don't buy these.

spin time is very short.  we have tons of beyblades and while these look like they'll be super fun, they're duds.  son won't even bother with it.

I think they'll be great. No ice or snow yet to try them out.

I am 100% sure they don't use them either. Please save your money. Just buy professional brands like Schiek or similar.

I need to return these. I just haven't had a moment to get it done yet.

unsure
I have not mounted the blades.
which is to say I have not used the blades.
which is to say I am unsure of the quality?.

I work at a skating rink and we just got a couple pairs of these to try out and they are terrible!! I have very narrow feet and these skates were pinching my heel (width wise) the entire time I wore them. The upper strap is also very flimsy, in comparison to any of the Spiritblade models (which are what my rink typically buys for rentals), which make it more difficult to get it buckled tight enough to skate. Also, while the wheels are a 78A durometer (compared to the 80A of the Spiritblades), on our wood skating floor, they felt very slick which made me feel as if I would slip and fall if I went any faster than a brisk walking speed. If you are looking at these skates I highly recommend ANY of the Spiritblades over these. The Spiritblades are very good for their price. Save your money and buy the right skate the first time.

I'm sure these are great skates, but its kind of hard to skate with two left skates. My daughter was excited for these, she put them on today and they are two left feet. Disappointed.

They looked like fine rotors, but they were never installed in the truck, they were sold with the truck uninstalled.

Not sure if they are unbreakable, but none have so far.

Right out of the package the middle sized pair had a good sized nick in one of the blades. I could feel the blade hang up on closing and upon inspection I noticed an alost 1/8" nick in the left sided blade. How something like that happened during manufacturing I can't imagine, but someone in QC should have caught and corrected it. No telling how many came off the assembly line before someone noticed.
Don't expect much if you choose this product.
I'm very disappointed.

Update: I was able to file down the nick in the medium scissors, it's still visible, but not noticeable in the shearing action.
Looking closer at the large pair I've also noticed it's flawed as well. About an inch from the tip, there's about a 3/4"1/8" sliver that either didn't get the titanium powder coating, or was taken off by the sharpening grinder.
I think the Chinese manufacturers are getting a good laugh out of selling this junk to America.

We ordered these for my son for Christmas.  He blew out the bearings on them the 2nd or 3rd time he wore them.  We just traded out the wheels with a pair I no longer use.  Not real impressed with the wheels, but the boots seem tob e good quality.  I did not request repair/replacement, but still can't give the item a 5-star rating.

My cutters arrived with the only contact between jaws being right at the tip. There was near an 1/8" gap between the blades everywhere else. That means they would never cut all the way through something. In my opinion there is no pride in workmanship in this company. And they apparently have no quality control department. That would explain the cheap cost.

I installed the wheels and then tried them out on my street for 30-60 seconds. when I inspected the wheels after riding, I found small pebbles embedded in the wheel. when I pulled them out, part of the wheel material chipped off and cracked. the next day my friend rode it and large pieces broke off of the rear wheel. My friend said he tried to "drift". I believe that the material from which these wheels are constructed is unsuitable for the application for which they were intended. Even if my friend had not tried "drifting", I believe that the wheels would not have lasted long.

December 3, 2011 EDIT:
Shortly after purchasing these defective wheels, I contacted Axtion Systems and they sent me two new sets of wheels at no cost. This was very generous, and I never installed the wheels to test them but the urethane wheel material is visibly different than the defective set. So it might be the case that the defective set was a bad apple.
