I use them for 3 months (I 2).
I have recovered in a 3-watt laser frog.
the flow is enormous ... imagine the two together !!!!.
on the other hand it is clear that it must be used with liquid martin ..
do not over abuse it at parties, in a room ... very dense smoke.
fiablitee rating, it is too early to judge but ellles seem
sturdy and well finished, the remote is very complete ... for good service !!!!!
