I faced identical uncertainties and went through lots of material yet still felt unsure so I bought an inexpensive model thinking the cost wouldn't bother me if it turned out I didn't enjoy using it and it would provide a starting point for selecting another one later after trying this one. Reading further only increased my hesitation so I chose an affordable popular choice among users. Tell me about your choice and your impressions along with where that leads you. Mine arrived just now and right now I'm looking at clips about filling the tanks and similar topics.
I've grown weary of constantly placing my used single-use needles into the waste container that belongs to my neighbor since it feels so inefficient. Moving to a refillable injector device now appeals to me. After reviewing an online discussion that featured a side-by-side evaluation chart I noticed these devices seem to fall into two main groups with little middle ground low-quality generics versus premium branded models that include extras. The usefulness of certain extras isn't obvious to me so I'm curious about approaches for picking one. Does the wireless connectivity option deliver actual advantages or does it turn out mostly unnecessary as it first appears? I'm unclear on what those extension pieces do. It looks like some models leave part of a vial behind unless something additional gets attached. How do others organize multiple compounds when using these devices? Would dedicating separate vials to each reconstituted substance and limiting reuse to just one compound per vial make sense? I'm wondering about suitable places to find such items since the locations I looked at didn't seem like the strongest options.
