AT&T introduced its steaming service, Direct TV Now on November 30 with a low initial price for early adopters of only $35 a month for 120 channels. It’s obviously aimed at cord cutters looking for cheaper options to cable and satellite TV, although it has some limitations.

AT&T says those who sign up for the $35 a month price can keep that fee for as long as they keep the service, but the special deal only lasts until January 9.

Eventually, packages will range up to $70, with HBO and Cinemax for an additional $5 each, well under their standard $14.95 monthly price.It also offers 15,000 on demand titles, though perhaps not as many episodes of some shows as cable may offer.

You don’t need a set-top box or a contract, but you do need a device it is compatible with and a browser that it accepts. Right now those include Apple TV, iPhones and iPads, Amazon Fire TV devices, Chromecasts, Android phones and tablets, and computers. Other access for devices such as Roku TV and Amazon Fire tablets will be added in the future.

While its entry-level lineup includes AMC, CNBC, CNN, Discovery, Disney, ESPN, ESPNU, Fox News, MSNBC, NBC Sports, Nickelodeon and TBS, TCM, many more and some local broadcast channels, it does not include CBS or Showtime, perhaps the major drawback for would-be cord cutters. No “Big Bang Theory” unless you hook-up a separate antenna.

If you really are a cord-cutter, getting an HD broadcast antenna, which isn’t generally very expensive, would be a good supplemental service so you get all local broadcast stations anyway.

AT&T says negotiations with CBS are ongoing so that may change as the service evolves.

You can’t record shows the way you can with a DVR, which is a problem if you tend to watch a lot of shows later than original broadcast if it isn’t in the on demand list. Some reports have said set top boxes may come later.

We’ve tried out the service for a few weeks, both on a Samsung tablet and online. We couldn’t use our Firefox or Microsoft Edge browsers. It requires Chrome 50, Internet Explorer 11 plus, or Safari 8 plus.

We experienced some brief frozen screens, especially when a show begins streaming online. Some users early on experienced outages, but it was available whenever we signed in. The online version is sharp HD on our highspeed broadband connection. We didn’t watch as much on the tablet, which didn’t seem quite as sharp over the AT&T 4G service. On the other hand, if you’re an AT&T wireless customer, Direct TV now won’t count against your data plan, which is a real plus.

The channel lineup is actually a better than my regular Direct TV package, which is costing me $140 a month with three premium channels. So I’m considering signing up before January 9, getting a broadcast antenna, perhaps subscribing to Showtime’s streaming service.

I’d be well under that $140 fee even if I also subscribed to the upcoming CBS streaming service, which will be exclusive carrier of the new Star Trek series.

I’d have to get a device to send the online screen to my large flat screen TV, but I’d like to have one anyway.
