Wireless keyboard with Marvicks doesn't work properly

Question

It's not easy to post this article due it's Marvicks (?) / Apple wireless keyboard problem.
Once I'm at home, I use my MBP like a desktop by connecting with Apple wireless keyboard/mouse. Works Great!
Since a while, I updated to Marvicks with great experience, but my wireless keyboard doesn't react on some uppercase keys. So, what I can do is: switch to caps-lock then type the missing key or type on MBP keyboard to get "T".
Look to here and you will find which uppercase letter doesn't work:
(use only with right-shift combination) aAbcCdDeEfFghHiIjJkKlLmMnNoOpPqQrRsStuUvVwWxXyYzZ.
(use only with left-shift combination) aAbBcCdDeEfFgGhHiIjJkKlLmMnNoOpPqQrRsStuUvVwWxXyYzZ.
Don't work letters/function:
(right-shift combination) B, G, T
(left-shift combination)   T
"fn+delete"
Further, I have "Pinyin - Simplified" language installed. During Chinese input, I need switch to normal alphabet by activate "caps lock". This is an Easy and fast way to toggle between Chinese - English input. (much convinient than Language switch via mouse clicks).
My older OS (Leopard, S.L, Lion) works well, but Marvicks interpret differently. Once "caps lock" and I navigate with cursor keys, sometime it convert my typing into e.g.: "\[34334" (this is not the exactly right sample, due I can't simulate this at this moment), something like that. It looks like the "Escape sequences"
This is frustrating when I write my document without looking to the display regularly.
Please help with thanks!

Why don't you use the MBP's internal keyboard?  Does it also not work right?
Have you tried another external keyboard?  If not, you should do that.  If it works OK,  then you need to replace the one causing all this trouble.
