I also shaved my door handles and did not put poppers in.Am glad I didn't as I do not need them.When i pop the solenoids the doors open enough that I didn't need them.I wasn't a fan of putting them down in the sill as then there is uneven pressure on the door.Like Itoldyouso said the best case is to put them where there is even pressure.Some of those poppers have some substantial pressure.
