I sell both, actually can get your about 5 different brand units that try to do the same thing and don’t. I run the Sprint Booster in my Gallardo and 458. Sprint booster every time and I can put/choose from anything I want in my cars as I'm in the business. I’ll go into more detail later or you can call/text me anytime 717-319-2100 and I can explain any questions you may have.
I’ve also had the least amount of returns with Sprint Booster out of any of the others. I test everything. The newer version isn’t shown in here but also love how thin the Sprint Boosters wire is (allows for easy way to hide it OR you can completely REMOVE the controller after you set it (it will remember you setting in the firmware) for a fully stealth install which can’t be done with other units. @Itsagoodday
