Just in case you find a V Twin we are leaving our review of the discontinued device below.
This is the only belay device we tested that is made of stainless steel. Most belay devices use some form of aluminum. This gives the device a burly feel and cool look that sets it apart. It is the only device with friction teeth that don't wear down. DMM is known for its cool looking products and this is no exception.
For most climbers, we would recommend either the Black Diamond ATC XP or Wild Country VC Pro 2 over this. The V Twin performed well for lead belaying but did not offer much friction while lowering. Compared to the VC Pro 2 that costs $11 less, it is hard to recommend this unless you a) just really like the looks or b) want a super burly device that won't wear out.Canyoneers who frequently wear out belay devices due to the abrasion of sand on the rope may be particularly interested in the V Twin.
