Centrifuge received very quickly broken but I had to pay for the return shipping cost, and face after sales service almost non-existent and not very competent, I decided to cancel my order so that cost me expenses Port and back (nearly 20 euros in total !!) - I think that society treats its orders very quickly, but when there is a problem the customer service does not assume all returns. It's a shame as bad when there is a problem when one is as good when everything goes well. To each his trade policy - I do not recommend this company for fragile products (such lamps, electronic), etc .. because as indicated above, you must return the item at your expense - it is better not take risks - if you buy directly from Amazon, you support the cost of return in case of breakage or defective device.
