I just returned the 2nd Neotec Pro Tripod to Amazon within a week. Two of the three legs of the first tripod wouldn't lock into place. I figured it was a fluke so I exchanged it for another one and sure enough the 2nd tripod had a bad leg as well that wouldn't lock into place. Very frustrating! I called Manfrotto and, unlike other reviews I've read, their service department was quick to respond and very helpful. They said they would replace the leg for me under warranty and provide a fedex label. But after consideration I decided to return the tripod to Amazon and buy a different tripod. I really liked the idea of easily adjusting/leveling the tripod by pushing a single button on each leg but unfortunately I lost confidence in the design. I searched all over the net looking for others who've had a similar experience but to no avail. Perhaps this is an isolated incident but I'll feel more comfortable with lockable tripod legs.
