I think the reviews are off the mark, as you can go a substantial distance with the free version of burp, and none of the material strictly depends on burp--any intercepting proxy will do.

Similarly, the online stuff is totally optional, and none of the master WAHH crafstmen I know have needed that in the slightest.

It is pretty clear in reading those reviews that a person can, with no investment of time or effort, write bad reviews about anything.

It takes effort and energy to get the most out of WAHH, and you can do it without spending an additional dime.
