Likes, love the way the wheels light up, they have roller bearings, and the bracket seemed to be strong steel. Roll very tightly andquietly, And they fit right.Dislikes, the only thing that came in the box was the brackets and the wheels. But it only cost me four bucks to go down to the hardware store to get the bolts nuts and washers to bolt those wheels onto the brackets. And I had the extra nuts already to bolt the brackets on the bike… at first, I was going to send it back but the email to contact the company for support didn’t go thru. So I just decided to go spend the four bucks for the bolts. And kind of glad I did………Edited to add that the company saw my review and is reimbursing me for the hardware, I am very happy now… and they work great.

Easy to install and super cute light up wheel. Grandson had a blast learning to ride his bike!

I am returning these immediately. I attached them per instructions to my son's Trek bike. They worked fine ****IF***** he did nothing but ride in a straight line, but as soon as he tried to turn (thus putting more weight / force on them), they folded back and the bike tipped. I tightened the bolt on the wheel axle as tight as possible, but it was no use. Sliding still happened.I went into my local bike shop to see if they had any insights -- the bike technician said that the design is poor. High quality training wheels have brace / stabilizer arms that rests against the bike frame itself to prevent the issue I described above. I purchased such a set and it works like a charm (see second pic). The plain steel design is less attractive --- but it WORKS. He can now turn a corner without the bike tipping over.My recommendation to other customers is not to buy the PRUNUS set. The set I ultimately purchased is made by Wald (in business since 1905 .... they know what they are doing!). My recommendation to the folks at PRUNUS is to modify this set to include brace / stabilizer arms!

It is a beautiful product. Not universal, and could not fit the bike. And therefore the bolt and nut keeps being unscrewed. The design is really nice, and the lights well great. Unfortunately it's not sturdy enough. After 2 rides in the street, it bent.

Bought for my kids 20in bike. Awesome instructions with actual photos of the pieces and assembly. No silly diagrams. Comes with 2 wrenches (a small dingy one and a “real” wrench!). Also comes with a dandy socket style wrench with the end also serving as a Phillips screwdriver.Real high quality stuff. Sturdy wheels.the actual brackets are reinforced to prevent bending. Work like a charm. Adjust to any bike size. Fit my kid’s Guardian bike. And also cheaper than Guardian branded training wheels.

The original screw hole is too small to match an 18-inch bike. The quality is ok. We go to find bigger size screw to instead.

Great quality. Nothing cheap. Wheels are like scooter wheels so not loud. Work great.

it was an easy install and they seem to be very sturdy. My kid loves them. However, the lights don't seem to be as bright as I was expecting, but maybe it is because we haven't ridden them at night. good overall for the price.
