As a hesitant buyer, we were skeptical about purchasing this product, but we are so glad we did. Electronics-based, this stabilizer is the perfect tool for any videographer needing a little extra support. It is extremely easy to install and adjust, making on-the-go filming a breeze. Based on our own experience, we have found that the stabilizer greatly improved the quality of our shots by reducing shaky footage .The only con we can think of is the price point, but in this case you truly get what you pay for..
