I feel like the lasers are hitting the same spots with each use. is that ok, or should i shift the helmet a little with each use? (model evo lh40)

Actually, each time you wear the Theradome the lasers are hitting slightly different parts of your scalp. But the way lasers work, once they hit the scalp, each laser beam spreads out, similar to water hitting a sponge, so it absorbs then scatters. Therefore you do not have to worry about trying to move the Theradome around to try to hit all spots on your scalp. After 20 minutes all the lasers light will have spread around fully around your scalp as well as penetrated deep within your scalp to hit the hair follicles. Hope this helps. Theradome Support Team

Is there a way to turn off the speaker?

Thanks for your question! Please press the master switch to turn the helmet on. Then double click the master switch to adjust the volume. The word “Theradome” will be spoken at your chosen volume level. You may double click the switch to lower the settings, which will decrease from loud, medium, soft, and silent before looping back to loud.

Can the battery be replaced myself if it dies or will it have to be returned to manufacturer for battery replacement?

Changing the battery is straight forward and you don't need to send your helmet back to us to replace. We have simple instructions and a video if you prefer to go through how to replace.
