Not horrible, but half the wrench of it's predecessor (discontinued was $37.98 in 2023) which was double ended with a 17mm and a 22mm for the 3/8 and 1/2 inch drive nano sockets respectively. It retains the same flaw as the last one. It's lacks a reverse switch, which is problematic if you should be working in limited space (as it is designed to do) and can get stuck if the bolt doesn't have enough clearance to be removed.

The Astro has a grip-ring that holds the micro sockets from falling out. The Tekton does not have that feature.

The Astro is 100 tooth, the Tekton is only 72.so most people would miss the advantages of the Astro

HF Quinn has a set of low profile sockets that fit this, although often, they are more money than the genuine Astro ones.
At the time of this post, they are cheaper:

Good price on the wrench. No deal on the sockets but if you have them then this is killer!

I own the Astro ratchet wrench for the 3/8" Nano Sockets, and it's great! These wrenches have a retention ring that prevents the socket from falling out.
Great deal on the 1/2". I'm buying one. Thanks OP!

Is the Astro a better quality than the Quinn?

I have the Astro Tools 3/8" version, but I use the Tekton WRB35422 for my low profile HF Quinn 1/2" sockets. The Tekton is beefier than the Astro Tools, and is double ended with a flex head on one end and a fixed box on the other end. It's 17 inches long, a bit shorter than the Astro Tools. Tekton web site claims it has a proof torque of 450 ft lbs, nearly double the ASME standard for a 22mm flex head. Astro Tools doesn't give any info on proof torque for their wrench. Tekton is $36 but worth it.

The Astro states that it is made for the Nano sockets, the Tekton does not....not sure if that makes a difference.

No difference. You can use the Astro Tools nano sockets or HF Quinn sockets with any 22mm wrench. Olsa Tools also makes the nano sockets with a 22mm external hex.

The Astro has a retainer for the nano sockets… does the Tekton?
