Unsure..
Iv only had my cap for a week so far, so i can’t comment on how it is going so far. However, when the product arrived it was in a rather strange bag with absolutely no packaging instructions or paperwork for the “cap”… the “cap” its self does not fit the insert (the part with the LED-LASER).. to be completely honest with you it almost looks like i have purchased something off of wish…. I do not know if the LED and laser diodes are what they say they are as advertised but I will keep using it with the hope its not a scam..
