Light-up features introduce a long list of new ways a statue can be "broken". Internal wiring channels, battery compartment, various wiring connections. So many potential points of failure - and you can't do nothing to fix them but complain to CS.
I don't see how "litterally anything [...] can stop working" is an argument. How can a statue without internal wiring, diodes and batteries/power plug "stop working"? As I say, I don't want this in a statue since I'd rather not live with the constant risk hanging over me that my collectible might drop in value due to some redundant feature that I turn on for a few minutes over the course of a year.
I don't see how "they're literally lightsabers" is a reason for them to include light-up features. Is your point that because the name of the weapon includes the part "light" that a statue rendition must then also include an actual light? Weird argument.
But hey, to each his/her own. I posted my opinion above and provided my reasoning. Your arguments are just weird...
I've btw owned a number of statues with light-up features. So my frustration with light-up features come from hands-on experience.
Count Dooku PF (weird flickering with light-up saber)
Darth Talon PF (saber lights up only a tiny bit at the hilt)
Shaak Ti PF (lights up OK)
Anakin Skywalker PF (also poor, and hardly noticable light)
Darh Malgus (flickering light, have to work the hand)
Thanos on Throne (weak and flickering light)
Iron Man Maquette (good light)
Iron Man life-size bust (good light)
etc.
