Overall, I am satisfied with this product sold by Micro Concept, it is a bit noisy ... I ordered and was delivered in good time. BUT, I do not know why, a 2nd order of the same Article was registered by Amazon and sent to Micro Concept that performed a 2nd delivery. Having found this dual I informed Micro Concept of error and they advised me to refuse the package and said that I will not be collected. I refused the parcel and I was taken by Amazon, to this day I expect a refund.
