They're supposed to be decent quality. Most of the SF members who've owned Testoni shoes have been happy with the quality. For an alternative in the same price range, you might want to give Meermin a shot.
That might not necessarily be true. The model in the link is 6'2" and he's wearing a 40S? For the OP who's 5'5", the sizing might be ok. Given his proportions, however, he might look top heavy with a DB and add to the short effect, IOW, a DB jacket is probably not his best choice.
