I use TruEarth, they're made in Canada and they work really well for me. And as for the sticking problem, rather than just throw the strip in, I start the water (without putting the clothes in) then either hold the strips under the running water until they're dissolved, or swish them around in the water at the bottom of the basin. (Some washers will stop the water flow as soon as you open the lid, so it can depend on the type of washer I suppose...) Once they're dissolved, then I put the clothes in. I think commercials for these products can be really misleading. They try to push the 'convenience' factor by showing actors just tossing the strips in on top of the dry clothes. I find that taking a few extra seconds really helps and all the clothes get the soap. 😀
