It is really good. I wanted to put the infinity on my psp and at first I was looking to get a duo pro with a large capacity but it was too expensive. This device brings life to the psp and I can download countless games and even for free. The speeds are much faster than the duo pro and even faster than the umd. Everything loads very quickly and now I can download and watch movies from there too

It works just fine.

The reason I give it 4 stars is because the plastic seems quite thin on one side, which concerns me a bit

Very good and does exactly what it promises! After jailbreaking it and loading it with 128gb, it works great.. it just freezes sometimes (e.g. in God of War during cinematic scenes.. never during gameplay!) but based on the comments I read, it might be because they say it doesn't work with more than 64gb. Also, if you have an adapter to put the SD card in your phone, you don't even need a computer to modify the PSP or load games.
Also, the loading times are reduced compared to the disc! Huge improvement!
Overall, if you have a PSP and want to relive the old days, it's definitely worth getting into it because the process is easy!

The plastic is so thin and it breaks so easily... Mine broke a little on the 6th time I took it out of the PSP, and after a few more times it just completely broke.

I put it in a Sony camera. Instead of a pro duo card that costs 50 €, I tried a micro SD to pro duo adapter, with good results.

Awesome tool. It revives the PSP and nostalgia is even better. Don't be afraid of the game getting stuck or not reading it (for modded ones always). It's a simple process of copying and pasting folders that is totally worth it!!! I recommend it 100%

It revived my PSP! I inserted a 64GB Samsung EVO SD card and now it can hold infinite things. Additionally, the read/write speed to/from the PSP via USB is significantly faster compared to the old memory stick card.

It's definitely worth it, if you get an SD card of 64GB or more, first format it on your computer to a FAT32 system and then insert it into the PSP, it will set it up and it will be ready. Prefer a 64GB one as it doesn't take long for the games to load in the menus.
