I had a LR. I successfully collected a lot of chrono data with it and thought it was superior to mounting a MS on the barrel as, at the time, that was the leading competing product.
Got a Garmin and gave my LR to my cousin who I love dearly and I wouldn't do that with an complete turd product.
However, I have a very negative view of the LR company...really a division of Infineon who apparently make very high end commercial doppler systems for a great deal of money.
I have never used, seen, nor know anybody who has the new little LR unit. However, I was not/am not interested in it at all due to my very negative view of the company. It takes years to build a good reputation and solid customer relationships and perhaps they will recover over time. But at the present...fuck no.
My complaints about LR...the company...have been stated here many times before and are quite simple....they did NOTHING over years to fix bugs and upgrade their product. They rested on their laurels, felt that they didn't have any competition, and did essentially nada, zip, zilch. It struck me as a "fuck the customers, we are the only game in town" attitude. So now, its fuck LR.
As for their app...IMO, it still sucked with significant flaws. Yeah, it stays connected to Bluetooth but my experience is, for just one example, when you try to delete an errant shot (from an adjacent shooter) via the app, you end up locking up the app and sometimes the unit itself. I've had to reboot my iPhone and the LR unit at times. And while BT transport may remain up...what's with it losing active knowledge of your unit??
I have not had any CS interface with LR, but there have been many reports of their awful and cavalier attitude to customers with issues.
So IMO, LR has a LOT of demonstrating to do that they have changed their stripes before I'll buy anything from them again.
