Unfortunately the product was very poor
I installed  the batteries and attempted to use this product it fell far below my expectations. I even purchased  new batteries to see if possibly the batteries that came with the product were bad but that was not the case. I immediately  attempted to return the item and was told I could not thankfully Amazon being the wonderful company they are did refund my money. This item does not work  as described and in no way is comparable to the Nikkon model.
