Mitutoyo solar is what I have and I love them. JG was not a fan but I have no idea what he's talking about when he says it doesn't hold zero?
And I never have to mess with batteries. Now, for cheap the Pittsburgh brand from Harbor Freight is pretty good. It's consistent with my Mitutoyo.
Starrett is good as is Brown & Sharpe.
Yours lost zero the day I used them.
Mine are Starrett EDP 64514. I got them from a friend. No telling how old they are. DO NOT drop you calipers on concrete, it is very bad for them.
