Question about Twinkly String

Great product, fun to play with the designs and colors. Just note the lights are a bit further spaced apart than expected. So to get an effect anywhere near what you see in the promo videos I would suggest getting longer length than usual. I usually get a 180cm tree and should have gotten the 32m string as the 20m looks fine as normal lights, but you lose the effect of any of the designs quite a bit.
