R4i 3ds for DSi Xl

I want to buy this flash cart but I'm unsure if it's compatible with the DSi XL.
Does anyone know?

I got it from nds-card. com But has a sticker from r4i-sdhc. hk
Also how do you buy from the website you recommended?

If it's an R4i then yes it is compatible with the DSiXL

Okay thanks.

Ethan is correct with the R4i he has suggested, if you want trouble free gaming.

Will the r4i sdhc 3ds work with the DSi 1.4.4?

Note helpful at the least.
There are many R4's, and nearly everyone released in the last year is like' R4i SDHC (Gold, Angrybirds) 3DS'.What card are you using.
A picture of it and the website listed on the card would be fantastic.
