10 years out of date? I lived in Israel between 2009-2011, I was a block away from the Beersheva preschool hit in Dec 2008 which first taught me about what rocket attacks were like. It sounded like a suitcase dropping on the ground. I don't know what it's been like since 2011 first-hand, but Wikipedia/current news tells me it's closer to my recall then yours. >90% are Qassams, because they're cheap, the launchers look like irrigation equipment, and the launcher team can scatter immediately after firing before the Israeli helicopters.
Here's a picture from Wiki of that Qassam hit
and yeah, the alarms work great, but people want active defense measures. Iron dome does that for them.
