The closest competitor to this unit is twice the price. The last 24 hours, we've used the trainer for several hours, and though yes there are complaints (the menu is confusing and takes time to get used to it for example), but there are so many qualities than shortcomings. Visual text reads out all the letters you type, there are multiple tests, identification by sound only training, wpm can be sped all.the way up to 50 wpm, or as slow as 5 wpm. I think the best part about this unit, is its a full training.unit, but it has a 3.5mm audio out Jack, so you can.either plug in headphones, or you can even connect it to a baofeng, tidradio, etc HT, and transmit Morse code without having a cw unit. So I can train, and I can transmit with the unit. If anything changes, I will update the review. But as of now, I'm incredibly impressed for the price. I don't know what the $140 unit is like in comparison, but if I can have all these features with minor complaints about construction or slightly confusing menu, I'll take it! What I can say, is this unit is much easier to figure out how to use, then it is parsing through all the information online to set up your own CW key station... oh, it also has a battery inside. So it doesn't always have to be plugged into the wall. I ran it for over an hour last night, no perceivable drop in battery percentage. Also, the screen is insanely bright. The picture was taken on the absolute LOWEST brightness, so.that gives you an idea of how insanely bright it gets. Could be good, could be bad, I suppose it depends on your purposes.

The first one I received didn’t work at all. Nothing. So I returned it and asked for replacement. Weeks went by without it being sent. So I canceled, got a refund and ordered another color. It was shipped and disappeared in tracking. Another refund. I gave up at that point. One failed unit and two failed shipments.

Ok, this little device is actually pretty cool. Pros: The main reason I purchased it was to practice sending CW with my iambic paddle, without having to disturb my radio setup. I plugged the paddle in, and it works without any issues. Built in speaker and headphone output Built in battery, I didn’t want to have to plug an external power supply in, the built in battery keeps the extra cables to a minimum Instant on - I noticed that once I set things up, the settings are saved, I can turn the device on by tapping the power button, and instantly start sending CW. You don’t have to re input settings each time, which was very convenient. I will primarily use the “Free Input” screen, it does exactly what I needed. The “CW Practice” screen is nicely done. Small size Comes with a nice carrying case. Price, can’t go wrong for $60. Cons: In the “free input” mode for sending CW, it occasionally a misses a dit if in the middle of a longer sequence like a “Q” (- - . -). I don’t think it is my paddle, as it doesn’t happen with my radio, something with the precision needed in the timing perhaps? It might be that my radio is more forgiving of me being a little sloppy, and this might help me have better timing? Either way it is only every once in a while. The “Listen Test” screen was a little confusing to me at first because the sound happens for one letter, while the display is showing the next letter. It is probably done that way so you have a moment to guess the letter before it shows it, but I still found it a little confusing.
