Review on 📱 Enhanced XRS521N-FM2 Replacement Remote Control for Vizio Sound Bar SB3251n-E, SB3621N-E8M, SB3621N-F8M, SB3651-E6, SB3651-F6, SB36512-F6, SB3831-D0, SB3851-D0, SB4031-D5, SB4051-D5, SB4451-C0, SB4531-D5, SB4551-D5 by Marcus Zimmerly

Including the one that came with the unit I had 4 of these in total, the last one seems to work fine. The problem that affected all the previous 3 was that they would drain the batteries even after not using them for 24-48 hours. Some have speculated that the faulty ones might have shorted out, but despite that I'm glad this one has held a charge for the past two weeks. Overall though, I think this is a poor cheap remote, mostly because the LEDs are so dim and hard to read. It's something like orange letters on a dark background. Bad design. Haven't found an inexpensive universal remote that covers all the different settings.
