Haul Gauge or similar for real time weight

[TBW Ventures]

Folks, in this forum there is always a healthy discussion about capacity of vehicles, weight of trailer/load etc. In many cases people are directed to go and weigh the truck and trailer. I came across this product recently (I have not yet purchased it), for a relatively small investment you could have real time weight feedback for the rig.

I was wondering 3 things related to this ;

Q1) does any one on this forum have experience with it?

Q2) q2are there others competitors? I am not big on seeming to promote one brand but i have not found an alternative.
Answer 2) I just found that Curt is releasing in Dec19 BetterWeigh.

Q3) this would seem to be a great solution to know your current load/capacity and occasionally calibrate with the government scales?

Thoughts out there?
