Replacing the need for a regular shaped diffuser the TriGrip diffusers utilise a triangular design which provides a much stronger and more stable structure. They also feature a moulded handle with securing strap, allowing accurate positioning with one hand. This means light can be diffused into awkward spots that would've previously required a stand system. The securing strap also allows you to support the reflector without actually gripping the handle, reducing pressure on your wrist and fingers when held for a long time.
