When they do a design change on some products, they do not change the product number so you could be getting something different than what you think you are getting.
I found out the hard way after I received some new flashlights in an order.
Like a 155 lumens flashlight when you should be getting 250 lumens flashlight.
Both have the same part number "88033".
155 lumens
