Used it once then I couldn't open it again. The metal shaft is connected to the canopy with a small weak plastic piece which broke the first time I closed the umbrella.
I contacted Repel to claim on their "Lifetime Replacement Guarantee" and was told that because I'd bought it from Amazon they couldn't do anything for me - "as we are not the seller therefore do not have access to this order".
So, the guarantee is useless unless you purchase directly from Repel.
I now have to return the broken umbrella to Amazon US (which is where it shipped from).
