Alert Lens is a great tool for my business. I like the ease of use and the fact that it is very customizable. The customer service is also excellent. I have had issues with the app crashing on my computer and also have had issues with the app not updating properly. I have also had to contact customer service about issues that I have had. I would highly recommend Alert Lens. Alert Lens allows me to manage my business and keep my customers informed on what is going on. I can also set up alerts to send out to my customers when changes occur.
