I have nothing to comment too much ... I have been collaborating with the Eakins Microscope Store for a long time. Over the years we have always received a high level of understanding and collaboration from EMS. If something cant not work (it happens, not EMS is to blame) to the required parameters, EMS immediately sent at his expense the respective part ... I received the package in excellent condition, everything was in place. I haven't tried what I bought, but I know that if something doesn't work ... it will be replaced by EMS immediately. Thanks EMS .....................
Bad seller, I do not recommend to buy from this seller, sent the product damaged, after video and photo evidence, in the face of clear evidence seller does not solve anyway, or you are lucky and aliexpress helps or the seller does not solve, absolutely to avoid, buy from others and forget this seller. For me, aliexpress gave a minimum refund but the product had to be fully refunded. Bad experience.
