Excellent stabilizer, you can attach and stabilize without SLR cameras, smartphones, action cameras and any cameras weighing up to 800 grams (replaces three stabilizers). There is a LED display, magic wheel, removable battery, WiFi, Bluetooth, phone apps, 1 year warranty. I've been using it for 2.5 months and nothing. In general, I am personally very pleased with the purchase and have no complaints.
