Comments about Nikon Nikon BL-3 Battery Chamber Cover for the F6 SLR Camera, and MBD-10 Battery Pack:
I've got one for each of the EN-EL4 batteries I carry around so that I don't have to waste time detaching a spent battery and attaching fresh one when shooting. And it comes with a spiffy padded carrying case that fits the combined BL-3/EN-EL4 unit to prevent damage when it's bouncing around in a bag.
Pricey for what it is and what it does though.
Comments about Nikon Nikon BL-3 Battery Chamber Cover for the F6 SLR Camera, and MBD-10 Battery Pack:
The price is the only thing holding back the 5th star. I have no idea of the build quality of an after market cover, but the Nikon BL-3 is sturdy and tolerances are tight. My opinion is inline with other reviewers, I believe Nikon should have supplied the BL-3 with the MB-D10. If you want 8 fps without alkaline batteries, the BL-3 is a must. No regrets here!
Comments about Nikon Nikon BL-3 Battery Chamber Cover for the F6 SLR Camera, and MBD-10 Battery Pack:
This little item is needed for the MB-D10 if you intend to use the EN-EL4 or EN-EL4a battery. You can use the battery pack without this upgraded battery but you won't get the 8 fps speed. I use this on my D300 for nature photography. The increased speed may sound like an unnecessary increase but it can make the difference between capturing the great image or missing it when there's a lot of action. I wasn't sure the increased speed was really important before I got this setup-- now I can't imagine not having it. It's Great!!
Comments about Nikon Nikon BL-3 Battery Chamber Cover for the F6 SLR Camera, and MBD-10 Battery Pack:
Its a needed accessory for the en-el4a battery for the D300 and D700. Maybe overpriced, or better yet it should come with the battery as a kit. I have 2 and have no complaints.

Works just the way that it should!
Comments about Nikon Nikon BL-3 Battery Chamber Cover for the F6 SLR Camera, and MBD-10 Battery Pack:
Very pricey for a piece of plastic, but it's necessary to purchase this piece to use EN-EL4a for MB-D10 grip. Nikon should have included this with the grip purchase.

Does what it does...well.
Comments about Nikon Nikon BL-3 Battery Chamber Cover for the F6 SLR Camera, and MBD-10 Battery Pack:
I also was stunned that this did not come with the MB-D10. Like all Nikon products this feels well built. Also the price, well it is Nikon. I also love the Neoprene Pouch that it comes in. If you own a D300/D700 and want more life out of your camera, both frames per sec and battery life, you need this piece to finish off the upgrade.
Comments about Nikon Nikon BL-3 Battery Chamber Cover for the F6 SLR Camera, and MBD-10 Battery Pack:
I didn't notice the tiny button on the top that needed to pushed up when inserting the Battery into the BL-3. Once I got the battery attached, the unit worked perfectly.
Comments about Nikon Nikon BL-3 Battery Chamber Cover for the F6 SLR Camera, and MBD-10 Battery Pack:
It was unclear that this part was necessary to make the D300 fire at 8 fps. Once I got it I had a moments trouble understanding how to connect the battery. No instructions provided.

Comments about Nikon Nikon BL-3 Battery Chamber Cover for the F6 SLR Camera, and MBD-10 Battery Pack:
This is not a required item for obtaining 8 frames/sec speed with D300. Due to the fact that not many retailers stock this item for a while, I used 8 AA size rechargeable to obtain 8 frames/sec speed on D300. Although I used mostly-trouble free eneloops, maintaing 8 AA batteries are still pain things to do, especially when you are traveling and staying on motel which offers not many AC outlet. So I purchased BL-3, EN-EL4a and MH-21 charger. EN-EL4a is not only lighter than 8 AA batteries, but also has an incredible stamina - can easily take more than 5000 shutter clicks with one charge. If you are sports/aviation shooter and using D300 I highly recommend this item. Personally think [$] for this piece is way too expensive, and I think Nikon should include this parts in MB-D10 package.
