Ordered this because it said it would work with the hottub I ordered. Received it promptly however did not receive hot tub till 3 months later.  Had a professional come out to install and it will not work with my hottub. Called to return it and was told cannot return because it is outside 30 days.  I explained wouldnt have known because we didnt even get the hot tub till after 3 months.  They would not refund me and stood firmly to the 30 days.  Not sure about cover lifter quality but their customer service sucks. Will not be ordering from this 3rd party company
