I only know of one Member who said he was going to buy a set similar to that about 3 years ago. Communication was by PM so there is no thread I can post and I don't remember the Members name.
Hew was in the same situation of needed 2 sizes of reamers.

But, there is no reason to suppose they would not work.

There is more the 5 Members that have bought the Laser Tool Fuel Injection Pump Sockets and I have also sold 5 of the same may years ago and no one has complained about them.
I think at least one of our Members has a Laser Tool Coil spring Compressor.

Concerning Laser Tool. I bought the first bunch of Fuel Injection Pump Sockets on eBay and they did not fit. I sent and eMail with pictures and dimensions to Laser Tool and ask them why the did not simply copy the dimensions of the Hazet Fuel Injection Pump Socket.

Not only did the get back to me they did something about the issue. About 3 Months later I got 5 free Fuel Injection Pump Sockets and they all fit perfectly. So they listened to me and fixed the problems.

Since I had a good experience with Laser Tools because they acted to fix the problem think I would go with that company .
However, I have no experience with their Glow Plug Reamers.

Ebay also sells similar sets and I think that includes the Laser Tool ones.
