I just got my first V4s and I can't inject with the concealable cap on. Same needles as I've been using with my V2 for months. Here's the link to needles I bought 3 months ago. https://www.amazon.com/dp/B0DSTYW1TP?th=1 Is there a trick I'm not aware of? The springy cap is hitting something and not allowing the needle to protrude fully. Only 1-2mm or so and on an angle. Any ideas? Quite disappointed with the 1st experience, I must say.
I started using V4s this week and have had an issue myself. Not that the cap doesn't depress but not getting depth with the needle length. I bought 4mm. I've just been taking that cap off to expose the whole tip. Don't want to waste what I have but would buy longer tips in the future.
Agreed. Mine are 6mm, but spring-cover was hitting the outer edge of the needle housing. Got different box of needles. This https://www.amazon.com/dp/B0GFW5DFY4?ref=ppx_yo2ov_dt_b_fed_asin_title seems to be a good fit.
