I have had the Rapsodo MLM for about a week now and I have to say that I LOVE this thing! I had tried the Garmin G80 but as a launch monitor, it just didn't do enough. I use Arccos for tech and tracking on the course, but I wanted something for practice, and the Rapsodo has been just awesome.I live about 5 minutes from a TopGolf so I go there quite often to practice. I have only taken the MLM there up to this point, but it's been great.SETUPSetup really is a breeze. The MLM only works on iOS right now, but from what I'm hearing, Android is in the works. You simply download the app, link it to your phone and you're good to go. The MLM device is already pre-calibrated, so it's as easy as connecting it to the phone, setting it up behind you (about 8 ft away, make sure that the phone can see you completely in the screen) and you're off and running!USING THE MLMBe sure to read the manual so you know what each light color means. In order to change your club in the software, you wave it in front of the camera and then turn over so the camera can see the number on the bottom of the club. The software easily recognized my irons and changes the club accordingly. It did not recognize my woods or my wedges well, however. It saw my PW, but not my 52, 56 or 60 degree wedges. In cases where the system doesn't recognize the club, simply select it in the software.Once you have the correct club selected, hit away! The MLM takes a video of your shot and gives you the carry distance, launch angle, club speed, ball speed and smash factor of every shot. It also uses the camera to give you a trajectory of your ball in the video. This worked about 95% of the time for me. I think it only missed trajectory once or twice. (See video for trajectory)The software also tracks how your shots land and distance of clubs. I put pictures of both my woods session and my irons session so you can see what the software tracks. It's great to see shot dispersion and distance of the different clubs. Totally gives me more confidence in my distances and placements. (You have to setup your GPS location as well as direction you're hitting to...I messed that up a bit as the map had me close to the right position, but the map picture was of the area before TopGolf was completed.)The system comes with a great case and is very protective. I love the ability to scrub the video of my swing. I can see my swing frame by frame to see what is going on...I can even share with others if I decide to take lessons.My only issue was for about 30 minutes I couldn't get the system to see my shots. It looked like it was working but wouldn't do anything. It was more than likely user error. I had grabbed my phone and ran to the bathroom so it lost bluetooth connection. Once I shut down the system/app then re-connected, all was fine.All in all, this is exactly what I'm looking for. Right now, it cannot be used indoors, but I did get an email from a Rapsodo rep stating that functionality just might be coming in the near future. I'm sure there won't be any trajectory tracking but we may be able to get the ball statistics and swing scrubbing.This has been a GREAT Christmas present! Looking forward to see how this will continue to help me in practice and lower my scores.
