I jumped on the Maven bandwagon early on. Ran a B2 9x45 bino for over 6 years and it never left me wanting. I sold my Leica Duovids 8-12x42 in favor of the Maven. I added a C1 8x42 for the kids to use and it is good glass. The C1 is NOT in the same class as their B series binos, but they are priced much lower as well. They seem to compete very well with other binos in that price class. A little narrow on FOV, but better image than the Vortex Viper HD which typically costs significantly more. And I own a CS1 spotter. Spotter is small, has a good image and is easy to pack. Not the same level as a Kowa 55 series for sure, but easily as good or better than my Vortex Razor that was a gen 1 65mm.
Last year, I picked up a Swarovski EL 8.5x42 for such a good deal, I couldn't pass it up. Ending up selling the Maven B2 to help replace the funds used on the Swaro. The ELs are better, but not by the margin one might be led to believe. The B2 is bulkier (but handles well in the hand) and holds its own with the EL. Several friends have (had) the B2 in the 11x45 configuration. Excellent glass, especially behind them on a tripod. The 9x45 has a better depth of field and was overall more comfortable for me to use. I also struggle with seeing my shake with a 10x or higher bino, so I finally settled on the 8-9x as it works better for me. And they are still fantastic on a tripod. One of my buddies sold his 11x45 after getting the newer B1.2 in 10x42. The B1.2 is right there optically, sharp to the edge and excellent view. Kept up with his B2 easily and in a much handier package. I personally liked the glass in the B1.2 and almost bought the 8x42 version, but ended up with those Swaros and stopped looking. I did think that the B1.2 10x42 was critical in the eye placement arena. My buddy didn't notice that, but I did. I have read so many excellent reviews on both the B1.2 in 8x and the B6 10x50 that I tend to think that those sizes are their sweetspot.
I also owned an 8x30 B3 bino for a while. Much preferred the view through them to the C1 8x42. They are AWESOME! But I was cash poor and optics rich, so I sold them to fund other projects. I am still shocked at how good they were on a tripod. And they were so light and "dainty".
Maven as a company has been terrific. I asked a lot of questions and they were always so fast to respond and help. After making a really stupid mistake with my B2 9x45, I had to send them in to get fixed. Not only were they fixed perfectly, they cleaned the lenses internally and made sure the armoring was perfect. Same serial number, or I would have thought that they just replaced them. And, they sent me a demo B2 9x45 to use during the remainder of my season while my bino was being repaired (they had to be sent to their facility in California to fix them, took about 3 weeks). Great folks, great product and they stand behind them.
Let me know if you have any other questions.
