I have a Beast I purchased from a member here in Feb 2013.
Only electric cart I've had. Replace the batteries in 2019.
Had to replace the controller due to possibly lightening hitting the shop about 4 years ago.
Had to replace 2 of the cables as well, as I let one of the connections get loose and almost burned up a battery.

I took the larger tires off it and put it on smaller tires on it right away, as the larger tires aren't needed on our place and I felt it would give me more miles and less strain on the cart.
It will spin the tires and throw your head back if you want.
It's 2wd but the rear differential is locked, and it makes a big difference.

Best advice I can give is to check the water levels in the batteries regularly, and don't ever let the level get low enough for the lead in the battery to be exposed.
Keep the batteries and terminals clean.

I'd buy another if needed.

God Bless,
David B.
