Seapath has been working great for us since we deployed it about 3 years ago! We have not had any issues at all using this product from day one through today's date of our contract renewal (which will be another year).
This software provides excellent support as well - their customer service team are very knowledgeable but also quick & efficient which makes things run smoothly!! There isn't much I dislike so far except perhaps some minor UI changes here n there over time due mostly just normal evolution/changeover period within IT environments across many different clients etc.. However these can easily resolved by contacting technical assistance if necessary via phone / email rather than waiting months until new version comes out without even knowing its going into production use again after being tested internally first before release?
