I agree, they're great! I had the Volt for a couple of years and it worked well but honestly, felt like I was vacuuming with an upright that had a hose sticking off the back. Makes sense considering it is based off the Riccar Supralite body. After that died, I tried the Perfect (lux) battery head but I didn't care for how it handled or looked with that gigantic battery sticking out the top.
I recently got the Wessel Werk EBK360 battery version and it's by far the best one of the three. It handles and works just as well as the electric version I've had for ten years. I use it with my hide a hose inlet as well as a Vacuflo Turbogrip low-voltage hose. It's nice to not have the bulky gas pump style grip.
