English to French Tech/Engineering Manufacturing Instructions

Dear French translators,

Please, let me know if the French translation below is correct, if not will you please give me your suggestion?

English phrase to be transalted into French:
This product cannot be used with Duo size slot hardware.

Comments:
"This product" means their new equipment such as USB flash memory.
"Duo" means MemoryStick Duo.
Memory Stick Duo is a half size of Memory Stick, so they want to say that their new product does not match a little slot for Memory Stick Duo.

Here the French translation:

"Ce produit n'est pas compatible avec les matériels à fente de taille Duo."

Please, let me know if this is correct.

Thanks in advance!

Doris
