The magnet issue is not unique to Maroo Moko. If you read the threads the magnet issue has presented in multiple cases from a wide range of manufactures. There are far more serious issues affecting the fit and security of the Ipad in other cases.
Maroo immediately contacted their supplier once an issue was reported. It seems it is an isolated issue effecting a few Moko cases at this point.
I have spoken to Beau, as well as exchanging emails regarding the magnet issue on the Moko. He advised me to continue to use the Moko case until the issue is resolved, have your wife continue to use her Moko case.Beau said regardless, the issue will be taken care of to insure all cases function as designed. Further, he said he will personally test the replacement case to insure proper operation. Remember the case is designed primarily to protect the Ipad,the smart function is a connivence only. The sole purpose of the magnet is to engage the sleep/wake function. The magnet does not function as a closure or to aid in securing the Ipad in the case.
You certainly can purchase another case, a case that may have bigger issues than the magnet. The Moko is doing 99% of what it was designed for, that is providing excellent protection to the Ipad. Good luck, enjoy your Ipad's,I am sure you will have a new Moko very shortly.
