The sheets are overall in very good shape.  The black sheet has a small bit of crumbling at the end at about the 1:00 position, due to bumping the edge on the table.  Both sheets are clean from glue -- I used water-based glue and it removed very easily.  They are cut to fit a Butterfly Kong Linghui paddle, which means they should fit similar paddles such as Timo Boll Spirit and Iolite.  I did not use any booster or anything on the rubber, just water-based glue.

 

I can think of three good reasons why you would buy used sheets of rubber: first, you might not be able to afford new rubber.  Second, you might want to just test the rubber (which is what I did) and you don't like the idea of spending a lot of money on a test.  Third, you might already use Express One and you want to pick up a couple of sheets cheap as a backup.

 

Just to give you my impression of Express One (sort of a mini-review): I foud the rubber to be very fast with medium spin.  It's faster, for example, than Tenergy but not as spiny.  The top sheet is not tacky at all, which I had trouble with because I used to play mostly with tacky top sheets.  It had excellent control.  Even though my loops were very fast, I had no trouble landing the ball consistently.  The main reason I didn't like the rubber is I wanted more spin, which I now get from Tenergy 05.  Also, Express One is a European-made tensor rubber, which means that -- like all European-made tensors -- it won't last all that long (by comparison, Tenergy lasts a long time).

 

Most American mail order places offer Express One at $44/sheet, but Dandoy is cheaper.  I'm offering the two sheets for $40 + shipping.  So that's about half-price.  If you are interested, please contact me at [email protected].
