We've got about 80 of the latest version 905's..
Been poking a few of them that have been modified to hold two CR2 batts for 6 volts and they work awesome..
Only drawback is that the CR2's have a limited life due to the cutoff voltage.. I get about 4 or 5 hours out of a set of batts which is not too bad but the vapor production is amazing even with a disposable 510 atty.. Old atties that are marginal seem to come back to life..
The new 905 appears to be set up for 6 volts as it flashes when the
batteries are low unlike the older version 905's..
We are waiting on more CR2
batteries to come in so we can offer a complete kit..
