I'm on the fence about them truthfully. I recieved my much delayed order of CR2s from them on the same day as @erktrek, and to be fair, they came through. But, the "in stock", but not really thing is very irritating to be honest.
Having said that, I've noticed this same BS with Amazon lately too. "In stock, will ship tomorrow if you order within the next 15, 14, 13 mins" then it suddenly has a shipping date two days hence when it goes in your cart.
The thing I've been noticing about Amazon is stealth price fluctuations.. I've had products in my cart jump $10 in price all of a sudden. You have to be very careful and pay attention.
This product started life around $43.00 and then when it was in my cart it jumped to $49 with no alert so I put it in the "save for later" holding spot. There it's bounced around in price here is the most recent.
Curious -- are they marketplace sellers or Amazon...I clearly need to keep a better eye on this. I remember in the early days, Amazon was a bit squirrelly with pricing, but back then it was variability between buyers....
Hey, I just had a problem with a dead Iris v2 sensor a while back as well, the security system was disconnected and it was pretty urgent. Then I saw someone recommend this CR2 battery in the forum. It's been stable for a couple months now. Hope it can help you!
