The only methodical review I've seen was done on the first of such devices
in recent memory, the infamous Buddy-L charger. The author concluded that
is does almost nothing.
There are newer and more aggressive microprocessor-based models out now,
like the Saitek (ECCO) and Remington NU-POWER models. These can have
moeerate success in topping off slightly-used new alkaline cells. If
you're careful about discharge you may get up to 5 extra shallow cycles
out of them.
The Renewals are designed to withstand the pressures generated by much
more aggressive recharging and, as such, can be reused significantly
longer than regular alkalines. They also seem to have a much better shelf
life than "rejuvenated" standard alkaline cells.
