Oh yes!
So far I've tried the HE versions of:
Tide, Tide with Downy, Tide Total Care (and some non-HE Tide powder just for the hell of it.)
Gain
Cheer
All Small & Mighty
And softeners:
Downy (various ones)
Snuggle (various ones)
I like all the ones I've tried, and all perform excellently, although Tide Total Care (and the matching Downy) smells pretty odd, although it cleans really well. Downy Total Care leaves a slightly waxy feel to clothes though.
April Fresh Downy smells lovely, it's shame we don't have a matching Lenor here, although we do have a Febreze "cotton" scent air freshener that smells exactly like it!
I'll be bringing some more back on my next US trip no doubt, including some of those new Tide Stain Release products I spotted on the website. You can't beat coming home with a suitcase packed with orange bottles...
If only there was a US equivalent of the Britsuperstore type websites, it'd save on the air fare!
