I have both the Olsa set and a Capri set. Both are fine for what they are. Not for high torque applications.
These two sets are identical.

I bought one Capri long form wrench for a specific task and it too has/had absolutely garbage fit. Turned me off the brand completely.I noticed a set of Husky brand on the rack in HD today. Not sure if that's available to you. I have the Capri set in SAE and the fit is pretty bad in my opinion. Low torque tool, I know. But shoddy tolerances aren't excusable because of that.
