As you can imagine, we love tripod ball heads. Platypods work well with almost any head but here are a few ball heads that we own, have tested and highly recommend. Please feel free to contact us with any questions.
Giottos MH1304-110c Mini Ballhead
Although the Platypod® Ultra is designed and built for heavy-duty use, that doesn't mean that it can't be used with lightweight or compact equipment. This is an extremely compact, inexpensive and lightweight solution that can support up to 7 lbs. Attaches directly to a camera's 1/4"–20 standard tripod socket. Great for compact point-and-shoot cameras and with smartphones and tablets when combined with tripod mounts from Square Jellyfish. Can also be purchased separately at Amazon and many fine camera stores.
