only my opinion, sure others disagree, but I think theyre crap. I've had two sets and they both either seized up or leaked in no time. I use hoselock style connectors from gardena with the tap on it, my current one has lasted 10 months and gets dragged and stepped on daily with no problems whatsoever and if it was to break I could easily source a replacement locally within an hour no need to pack up and order on line and wait a day or so for delivery, nuff said
