OnePlus is running a marketing stunt that in our view is both ill-advised and dangerous. It is offering the chance for 100 users in select countries to destroy a phone in an inventive way, in return for a 16GB OnePlus One for $1. There is a set list of phones eligible for the contest, all of them pretty new flagship models, including four Sony ones – the Xperia Z2, Xperia Z1, Xperia Z and Xperia Z Ultra. So if you were thinking about it, just don’t. We’re not sure we could bear it.
