I have tried several similar products and without doubt this is the smoothest and most intuitive of them all. It is packed with useful and easily accessible tools which make the product selection/buying decision straightforward. I'm still in the process of learning the ins and outs of SourceMogul and so far I am impressed. I like it very much. The only negative is the current number of suppliers that it searches is only 50; not a bad starting point but I look forward to more being added to the portfolio in due course. Would I recommend this product, without a doubt although perhaps it would be better as a well kept secret! I'd give it a 5 star rating.
The support from SourceMogul, particularly Ed has been first rate.
