These are NOT NiMH cells.

OK, it needs to be said.
These batteries have a significant advantage that overshadows their downfalls (don't like deep discharges; low capacity).
They are 1.5 volts. Not 1.25 like NiMH and other rechargables (Eneloop, or anything else you find called "rechargeable" - all NiMH). And they exhibit all the good behaviors of alkaline batteries: they can sit in a drawer for years and if they're fully charged, they'll be fully charged when you need them.
What does that prove? Well, they are useful in everything that a regular rechargeable ISN'T useful for: remotes, flashlights, thermostats, wireless keyboards/mice, rarely-used game controllers... those all are designed for non-rechargeable batteries because they operate around 3.0 volts, not 2.5 like what NiMH rechargeables do. NiMH also exhibits self-discharge at a much higher rate than alkaline. So if you let them sit in a drawer, they'll be dead.
That's why I've got a stock of both - NiMH for the cameras and... eh... that's about it. And I've got a bunch of iGo alkalines - these same batteries (but a 4-position charger) - for everything else. They work beautifully, and I occasionally swap batteries in the devices whenever I think about it to keep them from falling completely dead.
Despite their disadvantages, they're very useful in ways NiMH traditional rechargeables don't. I couldn't care less about the "non-toxic" or "green" effects... but they're just technologically superior in some ways than NiMHs are.

Five bucks off....that alone doeesn't make this much of a deal. Add in the $5 shipping...even less so.
Where is the Woot I made hundreds of purchases from?

Alkaline batteries do start off at a higher voltage, but that voltage declines steadily as the battery discharges, while NiMH batteries maintain a relatively constant voltage while discharging. This means that for over half the time the NiMH battery is actually putting out higher voltage.
Second, current low self-discharge NiMH batteries keep their charge for a long time and can last years per charge in low-drain devices like remote controls.
All that means is "well... NiMH are almost that good... they're passable now!". Rechargeable alkaline still have those advantages, but NiMH are merely "passable" as them. Still, point stands!

In the Darwinian world of retail merchandising, this kind of cell was introduced by one of the MAJOR brands more than 10 years ago and failed.
I was sent a set and a charger for review at the time. They said they could be charged "up to" 25 times, but each charge cycle held a little less power.
It was a pathetic attempt to wring the last bit of sales out of a dying technology.
NiMH cells were coming on strong, and if a tweak of existing alkaline cells to make the "recharge" could work, then the companies could go a bit slower about ramping up fabs for the newer technology.
Do you see these on the store shelves? No. You see NiMH cells, which keep getting better? Yes.
Another factor (to the delight of the big names) was that people continued to buy single-use cells, often because recharging was too much of hassle for them.
So the whole "alkalines are going down the tubes" scare that may have prompted this absurd experiment probably was for naught.

"90% of the negative reviews are caused by the use of the product rather than the product themselves."
Perhaps you mean the misuse of the product?

Every time some... (trying to find a nicer word than "complete freaking Pinky")... Unintelligent Consumer... writes a post here about how these batteries "ruined their charger", I want to apologize to iGo for the LEVEL OF HUMAN STUPIDITY they are faced with in their consumers.
The batteries. LOUDLY and OBVIOUSLY. Very clearly state that you are ONLY SUPPOSED TO USE iGo chargers with these. And they VERY CLEARLY say they're a distinct alkaline chemistry that is NOT supposed to be used in other chargers.
I wish it burned down your house so you might've learned a lesson... instead of bringing your ignorance here and parading around as if it's iGo's fault your charger got ruined.
(OK, not *really* wish your house burned down, that's kinda harsh. But seriously, coming around writing reviews because you couldn't spend 2 seconds even LOOKING at the battery label that says "CHARGE ONLY IN IGO CHARGER"? Darwin award would be fitting!)
By the way, I also have that same charger. With the capacity gauge on it, right? Yeah. I'm smart enough to know which batteries go in which freakin' charger...
