Some parts of the website are only in Chinese - such as their blog, where the most recent April 20 post translates roughly to "The female accountant can play high heels stepping up electric scooter" (translated by Google Translate).

While planetary gearing increases the low-end torque for hills and startup speed (both of which are positive things), it also adds complexity and may add additional noise. In the videos of the Stary you can definitely hear the motor and gear noise. This sound will only become more noticeable when the motor needs lubrication or is carrying a heavier load. By contrast, other boards on the market are growing quieter and quieter. Maintenance details of the planetary gears haven’t been released yet, but all gears require lubrication to prevent premature wear.

Almost all hub motors are a challenge to service. While it’s nice not to have belts to replace, the flip side is that worn or damaged items may need Stary service to be repaired properly. Replacing wheels may be expensive as they are not yet listed on Stary's website. Planetary gears incorporated into a hub motor is both unique and a standout feature, but it's also untried – and if it fails you have a 9lb paperweight instead of a skateboard.

A major con of any hub motor is the fact that the motor wheel is proprietary and wears out quickly. Generally these wheels are made of super thin urethane layers covering the motor, and can be expensive to replace. A standard skateboard wheel, by contrast, is relatively inexpensive. Additionally, the thinness of the wheel material transmits more road bumps and does not absorb shock as well as a similarly sized, normal skateboard wheel with the same hardness.

While a single motor will help with battery life, it also will have less power than a comparable dual motor. This will be more apparent for larger riders or those who want to go up larger hills. Planetary gearing will help with this, but it's still only a single 1,350 W motor (claimed wattage).

Stary is expected to ship in 2016 to Kickstarter backers.

The ventilation holes for the motor wheel are large enough that you can see all the copper coils inside. Water, grass, dust, pebbles, and more can surely enter the motor cavity through these vents. You will have to be very careful not to have things get lodged inside, and will need to air blow the vent holes frequently protect the motor and preserve its lifespan.

There has been at least one case where their Lithium polymer batteries has gone up in flames. This could have been due to misuse on the rider's part, or the battery could have been punctured. Generally LiPo batteries are safe - it is the same technology which has been used in phone batteries for years.

At times the board would disconnect from the so it would not react to go or stop from the hand remote controller. Must be updated

Most electric skateboards will clearly state maximum recommended rider weight. The only references on Stary's website is "To reach 18.6 mph with more than 90 kg load, we said ‘no’ to all the existing motor designs." What we can assume from this is that anyone at or above 200 lb should expect reduced performance (range and acceleration).

It takes forever for someone to respond.
