Are they like a belly band? I would recommend against using them for house training.
First, keep in mind your pup is young and needs a little time to develop his bladder fully. Frequent potty trips are a necessity for small pups. Don't wait for signs he needs to go. Take him when he wakes (from nighttime sleep and naps), after each meal, after or during playtime or any time that is exciting, and in between.
Restrict his freedom of movement in your home until he is trained. Keep him where you can supervise closely. When you can't watch, confine him to one small area with a washable floor, or an xpen. Give him more freedom as his potty habits develop.
Praise for every single good potty. My boys are 2 and 3 years old and we still praise for good potties -- indoors on pads, and outdoors.
We go really nuts -- woohoo! Great job! ...and other things I can't repeat here.
I often give a single kibble as a reward.
