Debra, lots of lots of people here just swear by the CE-3s. I use mine if it's all I have left. They are just too airy for me, and when new, they have (to me) a terrible plastic taste. I prefer the clearos.
But if you want to try the CE-3s, don't let the syringe-fill hold you back. I'm shaky at times, too, because of my lupus, and I didn't have any trouble with filling them. And mine never leaked at all. Just be careful not to increase the size of the hole made by the initial puncture with the needle. And yep, the needle is blunt-tipped, so you can't really hurt yourself with it.
Back to the clearos - I've been trying to be loyal to SI, and I will always get my batteries & accessories from them. SI has great batteries and superb customer service, but at $6.45 apiece, these clearos are way too pricey for short-term use. So far I've lost 3 of the seals from the 6 clearos I just bought. Mine are not yet leaking, so I hope they'll last. But there was definitely something "off" with this latest shipment. Imagine posted earlier that she's going to find out whether the factory changed the design. Hopefully, they'll be able to figure out why the seals aren't holding.
