I have never given a favorable rating for a purchased module until now. I've been waiting for something to actually impress me enough to warrant a favorable review. XMod 4.5 has done so... There is no doubt that XMod 4.5 is perhaps the most useful module I've purchased in the DNN universe, because it let me configure a solution my way. It's flexible and intuitive, and performing exactly as advertised. The documentation is clear and comprehensive, which says a lot when so many modules for sale lack decent documentation or lack it altogether. But far more impressive has been Kelly's responsiveness to my questions. Unlike other module developers, Kelly has gotten back to me promptly and stayed with me until my question was handled fully. So, I'm giving XMod the highest rating and, to date, this is the only module that has received it.
