"Seem good quality and are compact so easy to position. Bought these at the same time as a whole house repeller and it's not recommended to use them together (no point repelling mice then attracting them back with poison bait). The repeller is in the kitchen and has been effective so far, so I've placed these outside and in the loft as extra protection. Good that they are damp resistant."
