Performs as designed flawlessly.

None.

This bulk eraser makes a used tape like new again. I have used it so many times on some tapes that I lost count, but they still record with excellent clarity.

I haven''t seen any others mass-marketed. Faster than using the erase head on your VCR, that''s for sure.

This product is misadvertised. It''s not a BULK eraser. It has approx a 60 second on cycle, followed by a long (15 minute?) off cycle. You can get maybe 2 tapes done thoroughly before the off cycle. Sheesh.
