I have a Tennis Tutor Prolite Plus ( https://www.amazon.com/Tennis-Tutor-Prolite-Plus-Worldwide/dp/B086SG9VBS )

I'm pretty happy with it. Battery life has never been an issue. It's heavy, but that's because of the battery, I'm sure.

There is no remote but that hasn't been a huge bother.

It has a side to side oscillator which I love. I use it more often than not.

The speed is up to 75 MPH, and I definitely wouldn't want a machine slower than that. I have the speed set to 9 or 10 out of 10 on the dial all the time. It also has the option for topspin, which I leave on all of the time.

My machine does jam 10% of the time. Well, not really jam, but the balls can form a dome over the feed inlet such that none go in even though the feeder is circling.
