There’s only a handful of devices that will add network TV to a projector. For me the easy to see and feel blue mute button right on the corner was a deciding factor. If you scroll around a bit you can find the “date first offered” and that tells you how old the design is. This one is 2024 but many other devices are from 2019. The device itself is smaller than the remote but it’s working just fine. Good picture quality and bright colors.

Broke off my coax on my 80'. This was a great way to get my antenna channels back, and more affordable then the repair. Programmed all my channels and works as good as the tuner built into the set.

This should be avoided for many reasons, but I’ve listed the most important ones below:• This device is made from the cheapest possible components available. It will without a doubt fail in under a year. If you’re lucky, you’ll make it past the return window, when you can no longer return it.• You’ll definitely have signal issues, even with 100% quality and strength. Nothing you do will fix this because it’s due to using an ultra cheap tuner/receiver chip inside.• GUl (menu) is painfully slow and unresponsive due to lack of memory.• Remote is flimsy and slow to respond. Even if you do actually manage to figure out what the buttons do, you’ll just be waiting and waiting anyway.• Menus are confusing, and remain on-screen too long- like 60 seconds too long. If you don’t press exit, you’ll be waiting a full minute for them to go away.• Sound quality is poor, and sometimes doesn’t exist at all. Again, cheap components.• Don’t bother programming anything as it will reset itself to factory defaults in a day or two on its own. When this happened a third time, I boxed it up and returned it.This could be a great product, if they would’ve used ANY decent quality components, but when EVERY SINGLE COMPONENT is cheap, something will just inevitably fail. I’ll never understand why they don’t just use decent components and make a solid product…Anyway, do yourself a huge favor and just keep looking. Unless you just have time and money to waste, you don’t want this device.

I purchased this device to replace the absolute junk TV tuner on my Hitachi Roku TV set. If that's all I got from this tuner it would have been worth the money. Of course, once you have access to a feature, it becomes a 'must have'. This is where the work came in. The tuner was intermittent in DVR operation. In fact once I plugged in a SSD for recording things went real wonkey. I'd turn the tuner off at night only to find it on in the morning. Recording only worked once in a while. Fast forward/reverse buttons didn't work. As I increased the power supply first from using the TV to a 1 Amp supply, then to a 2 Amp supply things started working much better. The next issue was that recording wasn't dependable. I had less than a 500GB SSdrive, I attributed the problems to that. I increased the drive to try to record a whole hour but it was a mechanical hard drive and that caused it's own problems.The last change was to install a fast 1TB SSD. This is working pretty well. The functions I've tried so far are doing what they are supposed to.

Sort review is: it works fine for OTA. Longer review is: it took a while to set up. It unfortunately isn't HDMI CEC compliant so that caused some time delay during set up (I tried to hook it to the receiver but that was a waste of effort because of the lack of CEC). I thought it might be an issue with the supplied HDMI cable so I swapped the cable out but no luck. That's sort of a drag if you're trying to integrated it into an existing HDMI setup (TV, Receiver, Blue-Ray, etc all linked and talking to each other). So it's now connected directly to the TV and it works from there (with the extra step of changing the Input on the TV settings). As far as unit's remote goes, I added it to a SofaBaton. But because SB doesn't have a preset configuration for this particular Mediasonic unit I had to teach it some commands - including (because the CEC thing) a macro to get the unit, the TV and the Receiver to turn on and off at the same As far as picture goes I did end up swapping out the supplied HDMI cable because it didn't seem to feed properly when I set the resolution to 1080P 60hz. After that, the quality was nice and clear.Other than the above the unit works fine. It scans signals well, it has the added advantage of being able to scan individual stations in case you had to move the antenna, it's got an EPG for stations that provide it, it's user friendly, and it's IR receiver is fairly unobtrusive. There is a slight delay when switching channels but no big deal.I haven't tried the PVR stuff but other reviewers have so have a look there for their thoughts on it. One last note, if you're using an older TV (and components) with no USB connection available you'll have to get yourself an USB AC adapter because they don't provide one in the kit (look for a 5volt 3amp adapter).Would I buy the unit again, no, probably not. I'm too used the the convenience of HDMI products talking and co-operating with each other. But am I complaining about getting OTA back (I bought the unit because I blew out the antenna input on my TV), nope, the unit definitely got my OTA back.

After re-reading the instructions a few times as well as staring at the product and everything that came with it for a while, and then almost returning the item, I was able to figure out how to make it work. Basically, the remote is an IR remote, so the IR dongle has to be attached for the remote to work. And a working remote is essential for setting up the device - a channel scan needs to be done and video settings updated etc. One issue is that the device needed a stronger signal from the attached antenna than my TV tuner. If the signal is not strong the video keeps breaking up. One way to mitigate this issue somewhat is to set the resolution down to 480i - the picture was steadier then. I am going to try a signal amplifier I have lying around. I will update this review if this helps.In any case, this product more or less works, and it is low cost, so I am keeping it. But be aware of the issues above.

This is a nice bit of radio kit. Paired with a decent Yagi antenna this dongle will easily pull in digital braodcasting. I live in a city and I was able to scan for more than 50 channels.The setup interface in nice and simple. Hard to go wrong at this price point.

The HW135STB performs very well as an OTA tuner and OTA video recorder. Pulls in all OTA local stations just like my Samsung TV. After a bit of a learning curve (not any more than on any TV!), I find the user interface quite intuitive for channel surfing and recording/playback of OTA recordings. The instruction booklet guided me through all the features. I did encounter one problem. The unit would not fast-forward when watching recordings. A very necessary feature for skipping past unwanted segments of a broadcast recording. But the issue was successfully resolved when I contacted MediaSonicUSA's support via email. They provided a firmware update which was easy to install. Much better than returning to Amazon! Good customer support.
