I personally reviewed ~20 digital signage solutions and truDigital was the clear and obvious winner. They hit on all of our requirements and their customer service really won us over.
We use it to personalize greetings and our guest love it. It's fun, creative and generates a warm, friendly or professional atmosphere.
It's been a great communication tool for our front office. We use it to greet our customers that visit our headquarters and also to celebrate employee milestones.
It's got weird UI quirks that make navigating and customizing slides a painful experience.
Having to download each template to each playlist is a bit of a pain.
