Yeak. The Spruzza is a weird one, but apparently the experienced UK squonkers that sorta' decried the "no suction" are also really happily using them. Now, I am absolutely sure that there is A Way to stick in a regular silicone bottle, too - just not seen anyone do such.
Ketty, I bought a Hugo mechanical kit a month ago - no prior experience. I hate mechs and had forgotten that (the NC is an exception) - now, a month later, I ordered, received, modded and enjoy a Gbox 200 w/ soft-silicone bottle (removed Proprietary hw), a faceplate I modded for neomags (removed TORX screws), and squonk allllllll the time.
