I like 'em, esp. for my 30W Chana. Just recently bought two for $14 shipped + case. Can't complain.

Not a big sub-ohmer here, but I like having that extra cushion of safety just in case. ;)

I own a few Samsung. Vaping with one right now and I find them to hold a charge a long time and provide good hard hits. LG and Panasonic are also well made.
