Went with BMW recommendation but the engagement process was painful - prior to the installation approval I had to chase the team at every step following a totally unnecessary 2 week delay. Mixed messages - all done by phone so missed email only told be told subsequently that they could not call externally as phones were not enabled. Also expensive compared to alternatives - no spec provided for what I paid so no idea what I was getting. Once approved the installation team (outside contractors) were responsive, courteous and professional. Just wish I had checked Trust Pilot before engaging with BP Pulse as most of the experiences reflect mine.
