Stan, the grip was a Pixel Vecta. Bought from Amazon. The repair place was one of only 2 official Nikon offices in the United States. Their printed report stated: No problem found within standards. Checked battery drain. CKD AF operation. CDK Flash operation. CLN CCD. General Check & Clean.
Since my only problem disclosure to them was battery drain. they went far beyond that on an 8-month old camera, There was a recall in Sept for the EN EL 15 battery, so my battery is really only 5 months old.
Since they are Nikon, I would guess they are knowledgeable about electronics. I'll report back here after I've shot for a month or so. Currently, however, I'm only shooting about 200+ images in that period.
Bob, I joined Nikonians in May or June, so your warning about about off-brand grips might have appeared before then.
I'm ordering a new Nikon MB-D11 this morning. I want the warranty and I don't want drama. Digital drama or any other kind.
