I was surprised when I received my Nikon MB-D10 that it didn't come with a chamber cover when used with the EN-EL4/EN-EL4a battery, since I have never run into any one who has the MB-D10 who wasn't using one of those battery packs (versus the AA battery tray that comes with it).

Aside from that bit of dissatisfaction, the BL-3 bettery chamber cover is a set-it-and-forget-it accessory. It works just as you'd expect and I'd be surprised if you give it a second thought. Both the EN-EL4/EN-EL4a battery snaps solidly into the chamber cover and with a quarter turn of the gate is securely connected to the MB-D10 grip.

I bought this to use on the Zeikos battery grip. It works, but you have to really push hard to get the latch to engage with the grip. If you don't get a good latch, the battery can lose contact causing the camera to shut off unexpectedly. Also, it doesn't exactly fit this grip and Zeikos doesn't sell one (at least that I could find).

Come on, Nikon, just supply it with the grip. The asking price is a joke.

Fits like a charm, works like a professional item. Read the instruction to find the little switch to connect the battery with the cover! I sure would have liked a red circle around it - or a white arrow pointing to "open".
Sadly enough you MUST buy a separate battery charger at USD 100+ to charge the EN-EL4 or -4a battery. Why the battery cover could not integrate the charger-connection I don't know, but the extra charger increases clutter. Just as well that the battery is rated for some 1000 pictures, as otherwise you'd be carrying the charger for the camera-battery and the charger for the EN-EL4 (-a).

I think its a bit pricey for what it is... but it does come with a soft case that will fit the EN-EL4a with the cap attached... so whatever that's worth.

I wish it was just MB-D10 and everything was packaged in one price and not 3 different items.
first the MB-d10 and then BL-3 and then then charger

I purchased this unit for a backup battery that can be used on long trips. Works great when attached to MH-21 charger it saves having to carry charging equipment. I carry 2 for my MB-D10 along with a couple of extra camera batteries for my D300S Nikon Camera.

Quality built. This battery cover mates with the EN-EL4 quite well. Price wise it's very much overpriced, should be priced at about one-half the current selling price.

The BL-3 fits perfectly with EN-EL4a battery in the MB-D10 batter grip. I don't notice anything when I shoot. Just incredible amount of battery life for extensive shooting. IMO, this option addresses long shooting battery life needs and provides fast 8 shots per second. Shoots longer than NH-CD batteries. Different color code on the hinges to distinguish battery type. Works flawlessly--never think twice about it... Pretty much it.

Once again, Amazon gives the best deal--this time on the Nikon BL-3 which I am using on my D300 camera with the souped up en-el4 battery to get 8 frames per second shooting speed. For the best price of about 37 bucks I got the genuine Nikon product from Amazon, and in only 2 days again. You can't beat Amazon for great deals, and speed.
