I have ordered from them three times and have nothing but good things to say about them. Matt is very knowledgeable and helpful and their shipping is fast.
Just recently started buying through them myself. Excellent and speedy service, even posting all the way to Australia. They even handwrote a 'thank you' on my invoice.
I order strings from them with shipment to Poland. Never had problems - always arrive in about a week. They have much better prices then all Polish shops and as I play a custom set of Savarez strings I can buy every string separate which is impossible in Polish music shops.
