Go and have a look through your kids’ bedroom cupboard (or all over their floor if cleaning their room is their responsibility). How many of the electronic toys still work? 10%?
And yet they still play with the things, unless they’ve been so badly designed that all their functionality is lost once the batteries are out. I remember very clearly realising at the age of about 5 that battery-powered toys just limited the scope of play that your imagination allowed.
Toys that don’t contain batteries last longer, are easier to play with and are far more likely to still be in a condition where they can be passed on to someone else once your lighty has finished with them. And your kid won’t even notice the difference as he’ll be too busy playing with the box it came in anyway.
