Customer video review of SUBLUE EZ

Super easy to use and honestly just really fun. Took it out in the shallows and ended up staying in the water way longer than planned.

Customer photo review of SUBLUE EZ

Bought this mainly for my kids to use in the pool and on calm beach days, and it turned out to be exactly the right level for them. It has enough pull to make it exciting without feeling intimidating, and they figured out the controls almost immediately. What I like most is that I'm not constantly worried about them getting yanked around by something that’s too powerful. It has become one of those things that gets packed for every family water trip now.

We bought this for my 10 year old son. He LOVES it! It lasts a little over an hour. He loves the 2 speeds and cruising above and below the water. 10 out of 10 recommend. ☺️

Customer video review of Hagul EZ

My Grandchildren love the scooter, they love doing porpoise diving with it and divng deep in the pool. They race thru obstacles in the pool to see who can so it faster. They wish they each had one to race each other. Battery life is great. Wish it had a interchangable one like your other models. May have to consider buying another one. I have 4 grandchildren all who want to use. You have a great product.

Customer video review of Hagul EZ

Love, love, love it! Got it for my 9 year old son’s birthday, and now my other 2 older kids are begging for their own as they are all fighting for this one! They count the minutes for the charge light to show green. We will be taking it to use at the lake next weekend. Great product! **I never write reviews, but this one deserved it! 5 stars!!

Hagul EZ

Got this for the kids and they were into it straight away. Easy to control, not too powerful, and perfect for mucking around in the pool or calm water.

Very gentle power delivery and easy for my daughter to learn in the hotel pool

Hagul EZ

Für den Einstieg genau richtig und selbst mein Sohn kam nach wenigen Minuten damit zurecht

Hagul EZ

I have tested several entry level underwater scooters over the last two years and this one surprised me. The thrust feels much closer to the published specifications than many competitors. Power delivery is predictable instead of dropping off suddenly after the first few minutes and the removable battery design makes long sessions much more practical.

Hagul EZ

Llevo un yate de tamaño medio y buscaba algo sencillo para que los invitados disfrutaran sin complicaciones. Ha resultado ser mucho más útil de lo que esperaba. Todo el mundo aprende a manejarlo en pocos minutos y siempre vuelve con una sonrisa.

Hagul EZ

Für Einsteiger gut geeignet und leicht nachvollziehbar aufgebaut

Hagul EZ

I previously owned a couple of budget underwater scooters from online marketplaces and honestly the advertised speed and runtime were nowhere close to reality. This one feels much more transparent. For casual family outings around Sentosa and nearby beaches, it delivers exactly what I expected. The removable battery is also a huge advantage compared to many cheaper brands.

Hagul EZ

Good choice for younger riders near shore

Hagul EZ

I tried a cheaper scooter before this and the real performance was nowhere near the advertised specs it slowed down badly after only a few minutes and the battery could not even be removed for travel this one feels far more honest in actual use really like that the battery can be swapped out and the floating setup gave me peace of mind while snorkeling with my kids in Mallorca

Our kids loved using it near the resort dock
