Another fail

I am trying these min/max plugins here for a while and so far, not a single one has been tested sufficient enough. Here’s why that one is useless too:

It might properly prevent me from purchasing lets say 6 off a specific item if I set it up accordingly (max. qty 5).
But, if I purchase 1 off that item, then 5 again, I still get the message but the cart then gets loaded with two product lines of that product and guess what, its 1 off and 5 off.

Does anybody here on this site ever test their products enough? Especially if you want to impress potential customers with it in hope of making a living with a paid version.

This plugin does not what it should do. Maybe another one…
