The boosters are good, and soft. You can use them unfolded, or folded like regular boosters.
The boosters are great for increasing the absorbency of your briefs. I like that they are wider than other boosters, that I've tried. I have noticed that skinnier boosters will swell and feel like a wedge. But they are not too wide, so it should work within the leg guards.
I usually do not unfold them, instead I use them like a standard booster. My reasoning for this is that my thighs are larger than most, and they don't necessarily fit around me like I feel they should.
The boosters are thin enough to where the bulk of most briefs wont be increased.
I like the quality and the "engineering" here. It works well. The reason I don't give it top marks is because it is so very large and I use the pull ups for my handicapped daughter. It is meant for the tape on diaper. It is very difficult for me to position it right. It does hold a lot!!
