After owning a red cross line laser for years, I wouldn't get another unless battery life was critical
Good advice

One of the benefits of (most) of the Huepars is they can plug into the wall via USB C cable. This also allows them to be powered by a (cheap) powerbank that is longer lasting,more powerful than their batteries,and ultimately cheaper than AA batteries. Neither of these are options on my DeWalts or my Hilti but jobsite wise Hilti battery and Dewalt batteries are common if for some reason I would need to borrow from another tradesman. When we had 5-6 guys installing those of us with Dewalt or Hilti with 12v batteries would change out batteries once every 2-3-4 days, the smaller batteried Heupar (503cg) would get a change 1 time a day. The Bosch would need new AA batteries almost daily. If everyone stayed busy lasers would be in use 6-7 hours a day. Out of habit I would swap out my Makita 18v subcompact Impact Driver daily at lunch. Our habits for battery switches was born out of having a central location where our chop saw was set,where I cut aluminum angle all day, and I set up a charging station with batteries/chargers in an area of the jobsite with constant 110v power while the crew was installing on multi levels of an office tower. This prevented having to remember where things were plugged in, whose things were plugged in,etc.
It slices, it dices and makes julienne fries!
Why wouldn't you??
I have nothing but bad things to say about the GPL5. I owned one when it was a yellow RoboToolz, before it was rebranded in gray as Porter Cable, before it turned blue and became Bosch. Unlike the magnetically damped pendulum mechanisms used in just about every other self-leveling laser on the market, this POS relied on a motor to kick the laser into level. Except it moved in increments that meant that if you disturbed the laser and put it back in the same place, the plumb points would shift every time just a little. I NEVER had any faith in this, as the plumb points weren't repeatable enough to even set a door jamb.
Bluetooth isn't a significant battery drain (it consumes less power than simply sitting on the shelf), and lets you use your phone instead of a separate remote. A remote can turn planes on or off without disturbing the laser by touching buttons, or maybe you want to attach your laser near the ceiling and control it without getting on a ladder.
I wouldn't suggest Banggood ...unless you're looking for something else entirely,wrong currency,etc.
Huepar wasn't an option, and got tired of waiting for Milwaukee when I got the DeWalt 3 plane that runs about $500.
I got a robo laser decades ago and am still using it.
I had mine on a tripod 10' up and turning it off required I climb a ladder. I could see where you could use it for that.
