Pros extra batteries
Cons its not needed to replace the play and charge, which is good enough
Summary The play and charge kit is very convenient for me, because overnight when I need to, I just plug it into the USB on my computer, and I wake up with my controller charged. It needs charging maybe once every 2 weeks, so I don't see any hassle or problem. If you don't have a play and charge, go ahead and buy this, but if you have a play and charge, its not worth it.

Pros Basically ensures you will always be wireless!!!
Cons Sometimes - rarely - there are no cons
Summary CNET wrote that the fact that it takes 3 hours to charge is still a small con. Just because there is space for a con doesn't mean you should fill it in with junk. You buy two extra batteries in addition to the ones already in your controller and you always have two batteries on stand by, ready to go, after a switch-out in 5 seconds. So, after the very first 3-hour charge of both stand-by batteries, the need to charge again becomes moot, because by the time you use up the battery again you will have two always ready to go - no waiting. Hardly a con. This is an essential accessory if you have the wireless controllers.
Pros charge 2 batteries at once, fast
Cons only comes with 1 battery
Summary I will say i was able to pick this up for only $20 at best buy about a week ago and i am very happy with it. Before i got this i had just been using AA batteries and boy did my controllers suck them dry quick. My only complaint is that microsoft should include 2 batteries with this, especially since a lone battery is $11.99 and the controllers only come with the standard AA pack. other than that i suppose it is worth it in the long run as now i will always have a pack ready to go and won't have to spend more on AA's and i can always get more batteries in the future when i get more than the 2 controllers i have now.
Pros If you have more than two people who play 4 or more hours a day on average, this is practically a requirement. It charges reasonably fast and comes with a battery, plus it plugs into the wall.
Cons Well, first, it plugs into the the wall, so you can't hot-play, and you need at least one extra battery to be able to use this effectively.
Summary This is a handy peripheral for those gamers who already have batteries and play often enough to be taxing on the batteries. It's worth it to get this even if you have play and charge kits, but not strictly necessary. I'd suggest having at least two batteries per controller, however, just so that you don't have to deal with times of no play. As far as general quality goes, Microsoft Xbox hardware seems to be generally top notch. I've never seen a good reason to go to another provider, at least for this.
Pros Charge faster (3 hours)
Cons Takes three hours to charge... it's still long.
Summary The charger is good and is the best solution right now. Still, I'd like to see lithium batteries instead of the crappy rechargable AA batteries in a block of white plastic that looks like it's high tech while it's not. I mean, my ps3's controller takes around 30min to charge max. Still, right now, it's the best charger for the x360. I had the other charge kit wich needs to be plugged in the x360, and it's a pain in the neck since it's not charging while the x360 is off, so you have to plug it while playing, wich gives you... a wired controller. Anyway, I'm still hoping to see lithium batteries for the x360 too, for my ps3, my controller is charged full in 30min (around) and it last around 35 hours (around a month while I'm at the university). If a lithium pack pop on x360, buy it instead of any charger!
