New Astro 78300 flex head ratchet wrench for nano sockets. This is a pretty good first effort for making a low profile socket set with ratchet. What you get is about a 12 inch long 17 mm by 22 mm flex head ratcheting wrench. in the middle of the ratcheting boxed end is groove. in this groove is a thin piece of wire designed to retain the nano sockets, 17 mm for 3/8 drive nanos and 22 mm for your 1/2 drive nanos. The wrench itself is a little on the heavy side. The 22 mm end makes a great handle to hang on to while the 17 mm side is a little small to me. I like the concept of the flex head ratcheting wrench replacing a ratchet for lower profile but, i think i would rather have two separate wrenches. in fact, in fact I really want four wrenches

I want two, one in 17 mm & one in 22 mm that are like those single end, flex head ratcheting wrenches sold by Matco & Mountain. They have a ratcheting flex head spline end on a round rubber coated standard length handle.
The next two would be long pattern wrenches again in 17 & 22 mm but, with a flex head ratcheting boxed end on one side and a fixed boxed end on the other end for when you need more umph. The boxed ends would all need the groove for the wire retainers. On further thought, I think I could do with out the 22 mm sizes since I think I would mostly use the 3/8 drive nano sockets. although it's good to have options. The Astro 78300 runs around $50 which seems a little high to me even though i willingly picked one up

My initial impression is that it's a good first effort but, it left me wanting more.
