The most impressive thing about this product was it's ease of use, especially for small business owners who are looking to manage multiple campaigns without overwhelming themselves or running into technical problems! I didn't find anything in particular which stood out as being negative - just be sure you're comfortable with using your phone before trying telediiproducts because there may come a day when something doesn’t work quite right (although they have excellent customer support). Overall we were able reach more customers by increasing our response rate through automated emails compared to traditional telephone calls only reaching around 3% per month after over two years since implementation; however having access now via mobile has been very helpful allowing us greater flexibility than ever previously had available from landlines alone.
