All is OK, but the french translation of the products descriptions on your site is really very bad. Is it done by an automatic translator ? If yes, you should change it by a good human translator, because many of the products descriptions are totaly incomprehensible. How would you like to buy something, if you are not correctly informed ?
I ordered this battery and case on December 20, it was shipped on the same day, and I received it on January 9, which is pretty good for free delivery, well within the 10-20 business days estimated by MITB.
Additionally, I got it in the MITB pre-Christmas sale for 90% off, only 83c!
Yes, 83 cents - including delivery, seriously!
It is exactly as shown on the MITB web page. Just plug in the battery, put the case on, and you're good to go. You have to use the new case supplied, because the battery is so fat that the original case won't fit.
That's it, really. It does exactly what you'd expect. Great product, absolutely excellent value, free shipping! Thanks, MITB!
