Behind this Monster Adapter there is a guy, John Zhou from Beijing, China, who made a Minolta Vectis --> Sony E adapter for his own use sometimes in 2015.

At the request of a SAR reader and Dyxum forum member a first batch of seven units of this Minolta Vectis --> Sony E adapter was manufactured in October 2015 and listed on eBay.

The first adopter then made a review on Dyxum:

John Zhou then apparently disappeared until this summer when new Monster adapters surfaced, beginning with LA-EA4r, a re-engineered Sony LA-EA4 (Sony A --> Sony E autofocus adapter) with the translucent mirror and AF module removed, allowing the lens to make full use of the on-sensor phase detection autofocus capabilities of the latest Sony cameras, including Eye AF, Animal Eye AF and more.
The LA-VE1, the commercial version of the Minolta Vectis --> Sony E adapter from 2015, was launched and made available on eBay in October.

So, for the time being Monster is pretty much a one man's company with a contractor behind it manufacturing small batches of the adapters designed by John Zhou. It may seem a bit shaky; remember however that the Fringer venture,
Fringer whose adapters are so highly praised today, also begun with a guy somewhere in South-East Asia interested in using his Contax N and Contax 645 lenses with his Sony camera.
