Its major manufacturing flaw, which is why it gets 3 stars, is that every now and then, the middle battery pops up from the 3 and needs to be unscrewed/screwed back in, otherwise you will receive complaints and cries that it has stopped working.
Definitely read the instructions that explain how to activate them and that they automatically turn off after 30 minutes, otherwise it will drive you crazy because you will think they are not working.
I also tested the range and up to 280m it works fine, maybe with a little interference, even with houses and trees in between. Therefore, it will definitely work better with a clear line of sight.
If it weren't for the issue with the battery coming out of its compartment, which happened to both of mine, then the walkie talkie would be very good.

Excellent game. Easy to use, suitable for the age it is intended for (4+).
Very good range!

Overpriced like all products of this company. Very small and completely basic, it will satisfy children up to the age of 5, not more because it looks quite childish.
