Rhino 500 is the brand of cloth developed by Rhino to service their aftersales market and to get their brand name on to other peoples tables.
Quality wise it's a mid-range cloth comparable to Andy 600, they play about the same. Rhino 500 is just cheaper though with the cloth on a 8ft table costing about 6500 Baht installed (as opposed to 7000 Baht for Andy 600).
Rhino 500 is also slightly more durable (long lasting) than other cloths in it's price range and unlike most other cloths sold in Thailand, it will not slow down when the humidity is high.
Currently available in Powder Blue and Electric Blue - prices below do not include installation (installation by the Rhino installers available at 2500 Baht per table).
