    • You'd think for how much you're spending
So the probes that they sent with this item did not work I almost returned it but then I thought to myself try a different set of probes that I currently have already. Thank God I did because the concept is cool but for the money you think I could get a decent pair of probes not the cheapest probes they could find it's cool I don't know how accurate it is I should return it but I guess I'm going to keep it but you think that they would give you better probes dude you think it would be better quality dude Steve needs you ripping off people and you're making it hard for the community to get back into systems because your little items are expensive as hell shame on you ... show more

    • A must have for Car Audio Installers
Its a multimeter and amp dyno all in one... there's nothing else on the market like it unless you want to spend THOUSANDS of dollars. I've been doing csr audio for over 20 years and I wish we had these back in the day. ALL the SMD products are great.
