NIce. There is a problem with a battery compartment that contains plastic parts designed to hold the battery in place. However the same plastic part blocks a battery with a shorter positive port to reach the corresponding contact. There is a gap between battery port and the contact so it does not work. It is not a real problem as the contact can be easily bent to close the gap. However, it might be a good idea to place the contact closer to the positive port of the battery.
i haven't received my order, but the seller communicated perfectly
