Any thoughts on this brand?

I have 3 vtr10, 2 I bought new and one used and all work great. Easy to program with the pro gauge, no laptop needed like with the Tekin rs

I really want to try out the VTX8, but that price

it's $10 cheaper than the other major brands.

Price should never really be a factor even though it helps. I've been running viper ESCs a little over a year now and I can say nothing but good things, which is great for a new comer to the game.

I see that extra price go towards a true 365 day warranty and loads more adjustability than the 150amp hobbywing. I know some people don't use that many adjustments, but i do. Not to mention it's a better deal if you buy it with the progauge. Progauge separately $50, vtx8 separately is $190. Get them both together and its only $210. That's a $30 savings by buying the combo.
