I have used it for almost 6 years. I will always use them or a competitor going forward. I do all lockbox showings and the system works great. Some features will appeal to you and some won't, depending upon your management style. For example, I don't use their feature where I can text with prospects - others view that as one of the best features.
The one thing I would say is that their messaging system back to prospects doesn't work real well with the Zillow email addresses. So I do not have my Zillow leads forwarded directly into Tenant Turner. I take all of my leads from Zillow and manually enter only their name and phone number, so they get a text message inviting them to schedule a viewing.
For all advertising other than Zillow and a yard sign, I use their advertising syndication service and let leads from those sources flow directly into Tenant Turner.
Get the Sentrilock key boxes. I have had trouble with a few of the CodeBoxes and am switching to Sentrilock entirely.
Happy to answer any questions. --68.1.xxx.xx
