How do you not understand how you used the wrong adapters after observing that they did not work correctly and wrote about it here? According to your post you intentionally misused the press then complained about the function and cost of the press even though you knew exactly what it was before you purchased it. Just FYI the manufacturer describes the press thus:
"Economy Bearing Press. . .
The Press-4 package includes 2 handles and a threaded rod.
Press-4 is used with separately-purchased bearing adapters specific to the sealed bearings being installed (see links below). You may need to mix and match adapters for your specific use. Check bearing part numbers before ordering."

If you wanted cheap, why didn't you just use the Park adapters with a bolt and nut?
