The only thing HUAWIND has going for it is the novelty of its instruments. They have terrible shipping times and even worse customer care. It took forever for someone to get back to me when I contacted their support staff. They didn't seem concerned with my issues or willing to assist in any way. It took weeks to get a new instrument because the one I was sent was broken. Their incompetence and shoddy quality assurance are disappointing. If you're searching for a trustworthy business partner, don't go with HUAWIND.
