This is a good bang for the buck ball head for weights well under the specified 77.1lbs. I have a couple of specific uses that I need it to perform for: 1. It must be able to happily hold a 400mm 2.8 with my d810 and grip. I doesn't. Both the plate and ball head drift don't work for me.

I needed a larger head to stabalize my D850 and longer lenses. Most of the stuff out there is in the $400 range. This has the same diameter ball, smooth and rock solid locking mechanism and no extra weight at half the price

I bought this to replace a Monfrotto head for my Monfrotto tripod. Needed something easy to adjust, but extremely secure. Canon 5D MK4 with 100-400 lens needs to be really stable to avoid vibrations. This did the trick. I have a Sirui k-20x, but it isn't adequately stable for my needs.

Very rigid for my Nikon D500 and the pan feature is very handy.

I can't praise this ballhead highly enough. Very solid, beautifully engineered and smooth. Attention to detail is sublime. I use it with a dslr and 300mm lens. No sign of slipping or droop even over long periods.

Works well, Quality built. I decided to save a little money by going with the K-40x instead of spending three times the money on another pro head. Simple, easy to use,and high quality.

Love this ball head mount. Holds a lot of weight stable on my tripod.

Very impressed and happy with this ball head, especially for the money. Extremely smooth and very solid. I put my new Sony FE 100-400 w/ 2X extender on it and shot the moon. Effectively 1200mm on my A6300.

The fit and finish has the same appearance and luxurious feel of my Really Right Stuff accessories. The Surui arca-style clamp works perfectly with my RRS Nikon camera plate. I am delighted with the quality. The ball movement has the same feel of high quality.

This ball head was an upgrade from a very basic Flashpoint ball head. Night and day difference. I had read several reviews comparing different ball heads and this one always got excellent reviews and for the price I'm happy I went with the Sirui. First thing I noticed is the quality of the item.
