I have an Amvona Tripod with a "pistol grip" type head, an Amvona ballhead that I use on a smaller, more portable tripod and a largish Amvona bag.
All three were bought through eBay auctions. I paid relatively little for each of them. I think that they are worth more than I paid for them, but are worth less than some of the top quality brands.
I like the fact that both of my tripod heads use the same quick release plates, and that extra quick release plates were inexpensive, but dislike how difficult it was to actually order those extra plates at the same time as the tripod/ballhead orders (to save on shipping).
Their customer service staff were seemingly overwhelmed when I dealt with them about two years ago.
To date, everything has worked well except one quick release plate, which had part of the tightening knob break.
I would buy from them again, if I could get an appropriate price.
