"My last review was pretty bad. Since then I have worked with them and installed the new update and it actually works really well to both individual as well as group txt...though I&apos;ll only use for individual leads. There are a couple of small bugs they need to address but nothing that will keep me from using!"

"Just purchased the extension. Smooth install. One request... Can you make the button available on the detail page as well as list view ? I know many that search for a contact and there is no way to text them without going page by page through Leads or Contacts.Thanks."

"This short message service extension is awesome! works perfectly. Compared to other ones we tried, this supports Arabic (and likely other). The support group (especially Andrew) is very nice and very patient. They help us set up the application and fix some issues at our end(not in the app) via zoom. Great app, no negatives. Thank you for developing this! Transform my sales from 0 to 100."
