This is an exceptionally well made ball head. Of the three available sizes I use the MH7002, which is the largest and most sturdy, able to hold up to 8 kilos. However, they all function identically and even the largest is very lightweight.
I've used it on a tripod and monopod to great effect. The issue over the inadequate tilt is somewhat bogus as the head tilts a whole 180 degrees and swivels 360 degrees. The head allows for full adjustment in all directions, up down left, right, forward, & back whether on a tripod or monopod. I think the assumption from some reviewers is that the head should be able to pan when in the landscape (default) position thereby allowing the full 180 degree slot to be moved through 90 degrees without releasing the ball joint. This is not the case. The reason for this is the single adjustment lever used to allow both tilt and swivel. However, this means you can't use the head for tripod panning so it is unsuitable for video use. In essence, the device is a traditional photographic ball head suited for positioning the camera in a fixed position on a tripod.
The 3 spirit levels are accurate though a little small and not easy to read in subdued light or with a large dslr camera fitted. The levels do allow the head to be adjusted without the camera in place, which makes it easier to adjust.
The 5 year warranty is superb. The QR adaptor plate (MH652) is available separately and only costs about £20 so the head should be good for a lifetime's use.
I love the one I bought, the MH7002-652 and can't believe they are offered at such a low price. It's a device that one will grow to rely on because time and again it won't let you down. So long as it is used correctly of course.
