I doubt it's the batt. I would bet it's the tiny wire. I had one with an inline batt and it crapped out on me within 3 weeks.
But to answer your question, I can't. I have no idea.
they did not carry them at the one near me.. i bought a 4 pack on ebay for under $6..
decided to make a mod with parts from my passthrough and its a lot better..
Since I've already gone through 2 passthroughs, I think I'm going to hold out for a heavy duty one. I expect to pay plenty, but I really want this to work out this time. Hopefully a higher-dollar one will have a warranty with it.
Thanks Seabrook, I tried my best to make it as interesting as possible.That's a great, great review. You write so well. May put my order in after all. This will be my 3rd passthru. Thanks so much for a good review and for sharing.
