I did place a rubber arch support in them, but I do that with every pair that doesnt have a great one built in. I didnt understand why parents put their kids in these. Celular excelente comparado ao valor de todos os concorrentes de mercado, bateria realmente ótima, o que sinto na câmera é a falta de alguns recursos que são melhorados com outros softwares. Worth it if youre doing a lot of work online. It comes with a battery installed already and also a spare battery. It was a struggle but once past the slip on part, they fit great (if a bit shorter, snugger than typical 8s I have tried on). My fattie only has 4" tires. The only thing I didnt like is the connector design. Shes recommended them for me, but I want black. Took about 20 minutes to charge and I’m answering calls.
