Yup Poundland ones are great, bought some last year and a few have gone but most still going strong now.
I got one from poundland and it keeps filling up with water as well. I think this Wilko design looks a bit different so maybe it's better.
Give them a few weeks in this weather and they'll be full of water and dead. I even covered the top of the mini solar panel with clear adhesive tape and somehow the wet weather got into them (annoyed)
As above I picked one up in poundland on Monday,am very impressed with it as for a quid I didn't expect much but it's working well.Hot deal from me as they didn't have the warm white there so will go and get a couple of that colour from Wilko.
They sell these in Poundland. I bought a few for the garden. They have normal warm light solar led ones and colour changing ones
