I've only used this stabilizer 3 or 4 times and the 4th time it made a lot of buzzing noises, I don't know if that's normal or not but it made a noise like that. When I first turn it on, it literally stays on for just 2-5 seconds and then immediately goes off. until I press it about three times faster, it returns to its original position and actually stays that way. After all that's been said and done, I still love it, just don't know if it's flawed.
