I'll start off by saying that IPTV is more of a hobby for me than anything else. I usually prefer using Plex, Netflix or Kodi Addons for my media purposes.
Gears TV paired with the Mayfair Guide Pro is one of the best setups I've used and one of the closest things to a legit cable type experience. The EPG is very accurate and runs smooth, which is a deal breaker for me. I've tried IVUE before and the Simple IPTV Client and didn't like either compared to the Mayfair Guide Gears TV offers.
I have been using Gears TV for 4 months now and it has become my favorite iptv provider. I have used VaderStreams, Smoothstreams, Fab, Flawless, Epic, Streamhub Premium and Players Klub since getting into iptv and so far Gears TV has been the most reliable for me. I currently have Flawless and Streamhub Premium as my backup
Here's my setup: Using a FireTV with Kodi 17.3 100mpbs+ on my connection Mayfair Guide Pro addon through Kodi (APK available too) Price: Gears TV is $15 a month plus $2.50 a month for the Mayfair Guide Pro, but they also offer a free version.
I started using Gears TV a few months ago when they had some free trials going on and was impressed with the quality. I signed up shortly after and they started having massive problems for about a week+, but I stuck with them and used Fab as my backup in the meantime. After their major cluster fuck (which seems all IPTV providers go through every once and awhile) they have been rock solid ever since. I have been able to watch hours at a time without any issues. I used them during the Mayweather fight and it was solid the whole night.
Customer service is questionable as you can see from other reviews on here, but I haven't had to contact them about any issues in 4 months. After looking through their Facebook group they deal with a lot of pain in the ass customers too. It's IPTV though, so what the fuck do you want? Most major cable companies give you shit customer service too.
That being said, they run a Facebook group that keeps a pretty updated list of down channels. I have seen as many of 40+ channels down to as little has 5+ down. Either way they keep you pretty updated when it comes to down channels. I would recommend following them on Facebook and watching the down channel thread to see if a channel you really love always seems to be down. I would say on average a channel is down for about a day or two.
As far as a channel list they have about every major US/CA channel I can think of plus a bunch of UK channels. No VOD or catchup. Some 24/7 channels work apparently, but I've never used them.
I would recommend Gears TV if you want a strictly US channel focused service with a really good EPG. They have all the standard UK channels as a bonus too.
Edit: here is the site I use from their Facebook group https://hostingbros.net/acc/cart.php
