We’re Closing!

Gadget Infinity started almost a decade ago, sourcing the best price-performance photographic and two-way radio gear for fellow photography enthusiasts. It has been a wonderful journey sharing the many location portrait techniques with you on our YouTube channel. Over the years our passion in flash photography grew so much that we ventured into creating our own wireless flash triggering system – Cactus.

Starting next month, we will be putting all of our time and effort into product development at Cactus so we will be closing our operation at Gadget Infinity on August 30, 2016. Rest assured, the 30-day return policy still applies on your orders made on or before the date of our store closure. If you have any questions or concerns, please contact us at service@gadgetinfinity.com.

It will be a good bye but not a sad one as we will still stick around. Come visit us at

Thank you again for your support over the years and best wishes!
