Dishonest pricing, questionable quality, and false advertising. I am a pianist, and piano teacher. Given my experience, I would strongly advise the public, and all music students and teachers to avoid this shop. I bought 4 brand new "AMS KX90 Piano Castor Cup Single Small Plastic – Black" from Australian Piano Warehouse at $8 each, plus $9.95 shipping, a total of $55. The first cups shipped were a completely different brand of cups, that were clearly used (they had scuff marks, dents, scratches, and sticky residue from very obvious prior piano wheel usage). After contacting support, they eventually sent out another set of cups from Dale Cleves Music, which clearly marked them as $2.95 cups. I was charged above a 260% markup!! This second set of cups have clear moulding and tool defects, which gives me no faith whatsoever in their quality and safety. They also look completely different to the cups pictured on the Australian Piano Warehouse website which is blatant false advertising. I deliberately went to a piano specific company to ensure I purchased a high quality product. If I had known that I would just be receiving poor-quality cups I would have just gone to eBay directly which would have cost $13, instead of $55. Avoid all Australian Piano Warehouses and Dale Cleves Music Shops - what a waste of money, time, and hassle for a subpar product.
