For iPads

Note: The links given below are for specific models of devices. Please check the iPad model and size before buying.

For USA 

1. Attainment’s GoNow case  (link for USA)

As per a parent's feedback: "The case is very sturdy. It is a rigid plastic that has proven to be bite-proof as well as drop-proof. It has a built-in handle and offers some acoustic sound amplification, as well as the ability to attach a carry strap. It can only be removed with a screwdriver. We have never broken an iPad inside these cases despite frequent drops and throws".  

Note: Please check the iPad model number for the size that fits your device. 

2. The Rug-Ed pro-lock case (link for USA)

As per a parent's feedback "This is also very good (but not bite-proof). It has more bounce than Attainments’s and also supports a carry strap. It can also only removed with a tool. It’s less expensive than Attainment’s case. Rug-Ed’s Buddy case is advertised as more protective and good for kids, but we found it less protective than the Pro-Lock."
