Sonicare Philips Genuine E-Series Replacement Toothbrush Heads, 2 Brush Heads, White, Frustration Free Packaging, HX7022/30

This Phiips numbering is confusing, I have an e Series, but received the wrong brushes before. Will both HX7022 and HX7002 work in my holder?

I'm trying to find out if these HX7022/30 replacement brush heads will work for my HX7002/82?

What's the difference between frustration free packaging and standard packaging?

Who sells a sonicare elite hx7100 replacement handle/base & plug-in charger? (already have many replacement brushes)
