Valeton's Dapper unit was featured here recently: CLICK. It's a direct competition to Tech 21's Fly Rig 5, no secret about it. Things are getting more compact come 2017 as the Dapper gets a MINI version seen here. I own a Valeton overdrive unit, it's above average but I wish more of the manufacturer's products are brought in come 2017. Like Moer & Hotone, the Valeton name hold its own when it comes to sensible offerings albeit the obscurity.
