I bought two sets of these and the strings between the lights were done incorrectly .... one set the error (string was tangled inbetween last two lights .. it was not a "tangle issue" that could be undone but actually manufactured or put togather with the end string literally inbetween two bulbs with no way to undo it! At least that one I will be able to string up (not the most attractive since there is a little bundle of string at the end ..  but the second set the same thing happend but it was inbetween lights in the middle of the string so impossible to correct ... I will have to return .. hope the return process is easy with Wayfair!  So far I have bought two things .. one had a LOT more assemble then I dremed of and then these lights both being flawed right out of the box!
