I would try the MVP 2, if you're ok with non-replaceable batteries. I have the SVD and the MVP 2, and now I prefer the MVP. But, I'm kind of angry with my SVD because my 510 threads are useless, now (it's about 10 months old), and I am not a clearo fan. My husband is taking that one once my new device arrives. Otherwise, I like the SVD a lot. It's well build overall, and very solid. Apparently the thread issue isn't common. The MVP is also pretty solid, but some toppers won't make a good connection on it. I think that's just a clearo problem, though.
