[Twist Lock] I found this to be just the right size for a Gorillapod tripod and a perfect compliment for micro-4/3rds gear. Add to it ARCA compatibility and a low price and it is a definite winner.

[3 Positions] This looks like a great tripod head. Well made, sturdy, small and lightweight.
I converted my REI Hiker Power Lock staff into a monopod using this ballhead and the Op/TECH USA wrist strap. Just unscrew the cork ball covering the camera mount threads, put on the included thread adapter, then wrap the wrist strap connection loop around the screw and screw the tripod head on. This tripod head is light enough not to make the hiking staff not too top heavy like other heads do. I love it.

[3/8"-16 Male] I wanted a compact ballhead to use with a Platypod Ultra and this meets my needs completely. Unless you use an L bracket portrait orientation would be an issue but as I have L brackets on both of my OMD EM-1s I don’t have that problem. I like the spring loaded mechanism that enables the repositioning of the ball release/lock lever to what best suits you.

[4] This is a great and affordable ballhead that I use primarily for overhead camera setup. I have this on a C-Stand and Arm Extension and it uses an Arca Swiss mount which I have plenty of. This really is a simple to use and simple to setup. I personally use a Impact Superclamp and Manfrotto 037 Reversible Short Stud, with 3/8 & 1/4-20 Threads, with all 3 combined it creates a sturdy setup which will hold my camera steady and safe. Highly recommended if you need a ball head for overhead camera shots.

[4.66 lb] I needed a low profile ball head to handle a Sony FS7 on a Cinetics Axis Motion Control System and this one has proven very reliable.

[Carbon Fiber] This seems to be a very good copy of RRS small bullhead. I use it on on Gitzo 0 series tripod as well as Sunwayfoto own table tripod also a RRS clone. It is a perfect setup for some occasions.

[Carbon Fiber] Some very nice things about the Sunway: 1) The panning base doesn't slip, even with my 1Ds2 body and 300/4 lens. That's a pleasant surprise, and my biggest pet peeve about some other high-end heads, i.e. the Markins (I use a Q3 on my smaller tripod). The panning lock knob is larger than any other I've seen, all metal with large teeth to grip, and very smooth in its action. 2) The friction/lock knob also works like a charm. As with the panning knob, it's very large and easy to grip, and very smooth to operate. Most often I'll set the friction knob (on any head) to allow the camera and lens to sit still when untouched, but allow movement when I apply some force. This friction level is easy to set on the Sunway, and another big surprise, when I position the camera, let go, and then fully lock the knob, the ball position doesn't shift. This is a nice improvement from the previous Sunway DB-44 I tested last year, which allowed a long lens to pitch slightly forward. 3) This ballhead was delivered with a basic screw-type clamp, with index marks and an easy to see bubble level, but Sunway also makes a very nice lever clamp (which I've used with their DB-44), and a panning clamp I've read good reviews about. I'll guess one can order the XB-44 in any of those configurations.

[Twist Lock] I was surprised to read that this little ball head can take 10 pounds of gear.  Its really strong.  Im using it with my Nikon D500 with the
200-500 lens on a Manfrotto monopod. 
Yes I would buy it again.

[Carbon Fiber] I am using this ball head on a monopod with a micro 4/3 camera. I wanted the ability to take vertical photos. A ball head isn't usually the best choice for this (I would use a "L" bracket if I could find one that would work with my camera) but this unit has a bit of drag built into it that enables it to work well for this purpose. Combined with a very low profile, the ability to fit in a Pelican 1520 attached to the monopod, ARCA compatibility and a VERY IMPRESSIVE build quality for me it was the perfect product. This ball head is sold at a very low price point and it even includes with a small pouch for storage. While small it does lock securely and I would trust it with my D610 with a 70-300. (If it goes on back order again, be patient, B&H will ship it when it becomes available.)

[3/8"-16 Male] Nice ball head, especially at the price. Can do more than the cheapest Really Right Stuff ball head for much less money. Only fault I could force is that the clamp is not removable. I would recommend it to a friend.
