Both met the battery grip completely, the battery compartment is easy to handle cleanly. The closure is very rare times hakelig but probably also the battery compartment is not 100% plugged in there, but 1mm poking out (to myself). The fit to the camera itself is great, not so hakelig how I did it with a Phottix and 600D. The feel also what makes her, the smell of plasticizers is also quite low.
The original battery cover can clean and safe in the battery grip, incl. Locking area to park and is not just placed in a depression, as it is the case for one or the other battery grip.
The only shortcoming is that the first battery grip came unfortunately defective (the data link to the right battery could not be established). Thanks to Amazon, the exchange had a terrible problem. That reminds me such defects even at branded products from Canon have occurred on several occasions, there is of me for no penalty.
