Q: “I am having trouble opening the bottom cover of my Fireflyz, how can I remove it easily?”

A: The rubber o-ring that is seated between the Fireflyz housing and the bottom cover makes a water-tight seal but also makes it hard to remove the cover. Obtain a rubber mat jar opener like shown, and while grasping the Fireflyz body with one hand, use your other hand to press the jar opener mat against the bottom cover (do not grab the sides of the bottom cover or body) and rotate counterclockwise.

optionally, once the bottom cover is removed you can spread some Vaseline (petroleum jelly) with a Q-tip on the inside mating surface of the bottom cover to make repeated removals easier
