P3 kilowatt meters...whats the difference

So these two are on "sale" at newegg and i don't see the difference. Also are there other models? Can someone break this down for me because i don't see a huge difference besides one looks like it was made in the 90s and one is new






Newegg.com - P3 Kill A Watt Electricity Load Meter and Monitor



Newegg.com - Range Kleen P4460 Kill A Watt EZ Electricity Usage Monitor

 

The more expensive one has some added features like telling you actual operating cost to run things rather than you doing the math on your own. It also has a battery backup.

 

any opinions on which one to get? Also are they the same company? they show P3 on it but says its made by someone else so i am confused.

 

I dont know what you need it for, they are both made by P3, Newegg has a link directly to the manufactures product page at that.

 

thanks for the help i'll figure it out later on if the extra money is worth it but doesn't sound like it

 

well i bought the 4400? well thats what it says on the back of the device and i got it for 17 bucks off newegg and never again...broke in 2 weeks and newegg doesn't even have a return policy anymore. So now i got to do RMA through manufacturer and thats such a waste of time. Buying from amazon now on unless i get an unbeatable price from newegg.

EDIT: DUDE you look like a normal person in that picture

same chick is see ^-^ oles

 

lol, talking about me? when did I never not look like a normal person?

 

all i ahve seen is emo goth pictures lol the opposite of sandard american normal Maybe normal for sub groups I personally fit into the normal funny tshirt blue jeans group but the biggest dork in the world -_-

PS i'll still buy wheel off of you
