This is by far the best gadget I’ve ever used, I really need to use it a few thimes to get spiders out of my house!!!! my kids love it and I love it! Super easy to use and a brilliant design! My only complaint is that I wish the case was bigger and had a different top. It’s hard for my 5 year old to line the lid up properly so that it stays closed before he can carry it, if not lined up properly base falls off and everything in it comes out.
