I use my GoPro primarily to capture hiking videos. I've used other non-motorized handheld gimbals, but they were always difficult to balance and to calibrate and ultimately left me with videos that were shaky and that tended to drift from left to right. I knew I needed an electronic stabilizer, but most were out of my budget, costing between $250-400. However, at well under $200 I felt the Polaroid Stabilizer was worth a closer look.
I've been using the Polaroid Handheld 3-Axis Electronic Gimbal Stabilizer for several weeks now and I'm very pleased with the results I'm getting. It was easy to set up out of the box, and there was no need to download complicated firmware updates as is the case with other similarly priced stabilizers. The unit is quiet, easy to use, can be held at a variety of angles, and comes with three rechargeable batteries that can last up to two hours between charges.
My only complaints with the unit--and they're slight--have to do with the way the GoPro attaches to the stabilizer. The unit comes with an O-ring that that is placed around the GoPro lens and which is then attached to the stabilizer via a small thumbscrew. The thumbscrew itself is tiny, and while in the field I have to be very careful that I don't drop it, as finding it again would be difficult. Also, the O-ring fits VERY snugly and can be difficult to remove, and with it in place there is no room to attach filters to the lens. Finally, the small slot cut into the front of the stabilizer for attaching the O-ring is too small (at least on my unit), though this doesn't prevent solid attachment.
As I said, these complaints are minor, and they certainly don't keep me from recommending the Polaroid Handheld 3-Axis Electronic Gimbal Stabilizer to anyone looking for an excellent hand-held stabilizer for their GoPro at a very reasonable price.
