If you’re looking at light-up inline skates for your kid, you’ve probably seen the SULIFEEL Rainbow Unicorn and SUPER YOUNGSTER models. Both have 4-size adjustability and flashy wheels, but they have different builds and warranties that matter.
This comparison is for parents choosing between these two popular, highly-rated beginner skates. The main trade-off is between a lighter, well-reviewed classic and a newer model with a longer warranty. Let me show you which one wins and why.

Full Specs Comparison
I’ve laid out every key number from the product pages side-by-side so you can see the real differences at a glance.
The SULIFEEL is clearly lighter, which is a big plus for kids, but the SUPER YOUNGSTER fights back with a much longer warranty and a more detailed closure system.
Individual Product Breakdown
I looked at the real-world performance and specs for each skate. Here’s my honest take on who each one is really for, based on the details.
SULIFEEL Rainbow Unicorn Inline Skates for Girls Boys
4.8 stars (2,038 reviews) | 2.3 kg weight | 70mm wheels | ABEC-7 bearings

This is the proven crowd-pleaser. The 2.3 kg weight makes a noticeable difference for younger kids who are still building leg strength. I like that it lists a specific 70mm wheel size, and the triple protection closure (laces, strap, buckle) feels secure. It’s the best choice for most parents because of its massive review base and lighter build. The main limitation is the shorter 30-day warranty, which is standard but not as reassuring as a longer one.
✅ Pros
- Lighter at 2.3 kg, easier for kids to handle
- Huge social proof with 2,038 reviews
- Clear 70mm wheel size specification
- More color options, including fun spider designs
❌ Cons
- Only a 30-day replacement warranty
- Boot material is polypropylene, not as breathable

This is a strong newer contender that focuses on comfort and long-term security. The 1-year warranty is a major advantage, giving you peace of mind. I appreciate the mention of a breathable honeycomb upper and soft lining, which is great for active kids. It’s best for parents who prioritize a longer warranty and don’t mind a slightly heavier skate. The main drawback is the higher weight of 2.53 kg, which might be a bit more for a small beginner to maneuver.
✅ Pros
- Excellent 1-year manufacturer warranty
- Breathable honeycomb upper for better air flow
- Reinforced aluminum frame for stability
- Hook-and-loop closure included for easy adjustment
❌ Cons
- Heavier at 2.53 kg
- Smaller review pool of 271 ratings
- Wheel size not specified in the listed specs
Which One Should You Buy?
Both skates are great for beginners, but your specific needs will point you to the right one. I think the best choice comes down to what you value more: proven lightness or long-term security.
SULIFEEL Rainbow Unicorn Inline Skates is right for you if…
- You have a younger or smaller child and the lighter 2.3 kg weight is a priority.
- You want the reassurance of a massive 2,038-review track record.
- Your kid loves the specific rainbow unicorn or spider-man color themes.
Super Youngster Girls Inline Skates is right for you if…
- A 1-year warranty is a must-have for your peace of mind.
- Your child’s feet get sweaty and the breathable honeycomb upper is appealing.
- You prefer the modern gradient color designs over character themes.
❌ Who Should Skip All of These?
Skip these if your child is a serious skater looking for performance gear. These are adjustable beginner skates with light-up wheels for fun, not for advanced tricks or competitive speed skating.
For most parents buying a first pair of skates, I recommend the SULIFEEL. Its lighter weight and enormous number of happy customers make it the safer, more practical choice to get a kid rolling.
Frequently Asked Questions
Which kids’ light-up skates are lighter, SULIFEEL or SUPER YOUNGSTER?
The SULIFEEL skates are noticeably lighter. They weigh 2.3 kilograms, while the SUPER YOUNGSTER model comes in at 2.53 kilograms. For a small child, that difference of 0.23 kg (about half a pound) can make skating feel easier and less tiring. If low weight is your top priority, the SULIFEEL is the clear winner.
Which brand has a better warranty?
The SUPER YOUNGSTER skates have a much better warranty. They come with a 1-year manufacturer warranty, while the SULIFEEL only offers a 30-day free replacement policy. If you want long-term protection against defects, the SUPER YOUNGSTER is the better choice by a wide margin.
Are the wheels the same size on both skates?
I can only confirm the wheel size for the SULIFEEL, which are 70 millimeters. The SUPER YOUNGSTER product specs I reviewed did not list a specific wheel size. Both use polyurethane wheels and ABEC-7 bearings for a smooth ride, but if knowing the exact wheel dimension is important to you, the SULIFEEL provides that information.
Which skate is better for hot weather or sweaty feet?
The SUPER YOUNGSTER skates are better for breathability. They specifically mention a breathable honeycomb upper and soft comfort lining. The SULIFEEL boot is made of polypropylene, which isn’t described as breathable. If your child is active and prone to sweaty feet, the SUPER YOUNGSTER design is more suited for comfort.
Which one is more popular and has better reviews?
The SULIFEEL skates are far more popular and have a much larger review base. They have a 4.8-star rating from over 2,038 reviews. The SUPER YOUNGSTER also has a 4.8-star rating, but only from 271 reviews. For social proof and proven satisfaction, the SULIFEEL is the more established and reviewed product.
Do both skates fit the same age range?
Yes, both are 4-size adjustable skates designed for growing kids. The SUPER YOUNGSTER listing explicitly mentions ages 4-12. The SULIFEEL is also for kids and beginners. The key difference is that the SUPER YOUNGSTER offers an “X-Large – Adult” size option, so it can technically fit older teens or adults with smaller feet, giving it a slightly wider fit range.
My Final Verdict
My clear overall winner is the SULIFEEL Rainbow Unicorn Inline Skates. Its lighter 2.3 kg weight makes a real difference for kids, and it’s backed by the overwhelming confidence of over 2,038 reviews. The SUPER YOUNGSTER is a strong runner-up, best for parents who prioritize its 1-year warranty and breathable upper above all else.
If you’re stuck deciding, go with the SULIFEEL. For a child’s first pair of skates, proven ease of use and a lighter build are more valuable day-to-day than a longer warranty. You can’t go wrong with the crowd favorite.
