Pros:

This is a great tool. Saves from modding your original battery. Can be used as a Pandora Battery and a normal battery.
Nice led readout of battery levels.

Cons:

I've only used it in a PSP Phat (first generation) and I had to trim a little nub off the battery to make it fit. Other than that I have no cons about it.

Other Thoughts:

At first I bought a spare battery from ebay and was going to mod the original sony battery to make it a Pandora one. Then I saw this and thought it would be better, and it was!
I like that it has a dual purpose this way it's not something you use once and never use again. As a battery it has a good battery life.

Bottomline:

If you want to mod your PSP then get this for sure!

Pros:

I love that it's a lightweight and sturdy box. It's a great way to get use out of any spare 2.5 drives you may have.
No drivers needed!

Cons:

The only real con for me is that the hard drive isn't really secured to the case with screws. The drive plugs into the adapter and the adapter has 2 tiny screws that secure it on but there is nothing holding the drive directly to the case.

Other Thoughts:

I personally have a few of these. I use one to backup my music and video library, on for important documents, one for games, downloads and such, used to carry data from work to home or computer to computer. The uses are endless.

Bottomline:

Good quality and a great price. If you have spare drives laying around then you need this. Look on eBay or whatever to find cheap drives if you need one.

Pros:

Great card reader, works as advertised
worked with the cards I have, they are two gigabytes and four gigabytes cards. The 4gb is an SDHC card and there were no problems.

Cons:

the only con I can think of is the lack of an led. it would be nice it is had a light on to know when it was accessing the card.
That is the only con I have, KHAN!!!!

Other Thoughts:

Other thoughts? no, not really, I think I've said everything about this, I mean what else can I says? I wonder if I've hit 500 characters yet?

Bottomline:

Bottomline, Buy it, it's super cheap and as I've heard better than those really small tf readers they sell here.

Pros:

Pro's, well it works great, I have an r4 and am able to play Guitar hero on tour without any issues.

Cons:

the only cons I can see is that occasionally the buttons stick. If you press it and kind of slide off it easily it sticks, if you firmly press and release straight up then it's usually ok.
I also found after a while my hands was fatigued. It was ok for my 7 year old son but i find that your hand is in a bit of an awkward position when using it.

Other Thoughts:

It would be nice it if came with a pick, I'm sure it would be cheap enough to include.

Bottomline:

I guess overall it's good and for the price you can't go wrong, under $12 + R4ds = better than spending $60 at the store for the real thing.
