I ordered 14 Augustus this product. It took very long before I received the product. When I received it, it was broken. I contacted the seller and hij would send me new parts to repair. This also took much time. I asked again why I did not receive the parts. The seller told that they were lost wile shipping and would send new again. After waiting long again I deceided to dispute. The proposal from the seller was 6,88 euro or 34,38 and ship the defective product back. This shipment from Holland to china, costs 20-30 euro. That is not a solution. At the end of the dispute, Aliexpress choses the side of the seller and leaves the customer with the problem. The hole proces took 4 months !!! 1 tip, never, never, never, order at this seller !!!
Good working units, solid construction.
