Outwell telescopic transporter

I  must be getting older, we use the famous whale system for filling the van and have a couple of 25litre containers which give us days of aqua without  having to worry about the next fill up.. Whilst  we normally just  drive to the tap thought a small folding trolley might  be useful.
 
Outwell one looks tiny when packed but may not be that strong - so  what  if anything do you  use or have you tried the outwell  one!

Good thing I suppose is that  Lady Groundhog could also fetch the water....

I use 2 wheeled 25 ltr containers (1 for fresh and 1 for waste) so no need for trolley.
