This is a nice solid head for the price. I have arca Swiss on all of my stuff but my Vanguard tripod had some proprietary plate. I ended up replacing the whole head with this and it works well. My only gripe is that it's so solid, it adds some weight. This is good when it's vertical but when you're using it at an angle to reach out some strange location it is more prone to tipping over.

I was super disappointed in this. I bought it as it advertised as "low profile" an while it looks short and wide, it;s exactly the same height as my Oben ball head. It's also VERY heavy. The worst part is that the panoramic adjustment is unbelievably hard to turn, no matter where the knob is adjusted to....it takes TWO HANDS to move this thing on a tripod. The ball head is okay. It's not very smooth and it makes a bit of a scratchy noise while adjusting the ball to the desired position, but it seems to tighten down nicely. The ball sounds hollow. The device as a whole is very heavy, especially when compared to my Oben ballhead, which is just a basic head, and nothing fancy or expensive. I bought this "low profile" ballhead to use on my SkyGuiderPro star tracker, because it was supposed to be low profile for a lower center of gravity and light. It's neither, and added to the fact that is it impossible to adjust and would ruin my SkyGuiderPro gears if I tried to adjust it while on the tracker, I'm returning this and looking for an alternative low profile ballhead.
***Note: July 2020. The seller contacted me by email immediately after I posted this negative review and promised to send a replacement for this item, but it's been over 8 weeks and I have not received anything.
***Update: Nov 22nd, 2020. Seller contacted me again a few weeks ago, "shocked" that the replacement had not arrived yet and promised to send a new one if I would update my bad review to 5 stars. Well, I'm not updating a thing unless I have a product in hand that I am elated with. ......and still, no new ball head has arrived after me giving them my mailing address more than 3 times. Buyer beware.
****UPDATE December 28th, 2020: Seller contacted me again a week or so ago, and said they were shipping out a new ball head AND some extra items. I got the package today. The new ball head is great. It moves smoothly and holds tight. This is what I was hoping to get in July when this all started. They seller also included a small tabletop tripod and a camera strap. It seems they really do want to make things right for the customer and they especially value reviews. I'm upgrading this to a 5 star rating because the new item is exactly what I originally wanted and it works great. Please note, this transaction has clearly not been without issues, but the seller has gone to a considerable amount of effort (at their expense) to make good on their product. I would buy from them again if I needed to.

The tripod ball head is very sturdy and works perfectly even when very large lenses are on my cmera.

Great for spotting scope sturdy enough for a rifle just don't lean to hard

I purchased this ball head over 3 months ago. I found that the arca-swiss base plate attached to the ball head cannot be removed, which prevented me from installing some equipment directly to the ball head. I made a complain to the company with no response. The ball head is quite durable (so far) and can certainly bear 8-lb weight in a 45 degree tilted position with no issues. Last week, I received an email from the company to apologize for the delayed response because the message I sent was accidentally "ignored" due to their open-mailbox email address. They said they will send me a new ball head with no plate installed on it and the base-plate screw will not be glued to the ball head. Surely, they did send me a new ball head a week later and the base-plate can be removed freely. However, I didn't realize that there is a notch protruding out from the stem of the ball head to anchor the base-plate. Nevertheless, the customer service is excellent and corrected the oversight effectively and efficiently. I can easily put a shim to solve the notch issue. Now I can install some equipment onto the ball head directly. I thank the company for reaching out to me and solved my issue actively. By the way, they sent me a tripod gimble head to compensate my inconvenience, which was a nice consideration.
