I use mechs a lot but have a few vw
devices as well. To me each has it's own pros and cons but in the end it comes down to you. I choose mechs due to simplicity and lasting ability but mainly for looks. A mech to me is more on the line of artistic where as vw is function. Most vw devices to me, just don't have style and many don't care if they do or not. There is nothing wrong with that either but I like mods that work great and look great. I do though have a problem paying almost $200 for a mech. box mod when a hyper watt mod is cheaper, lol. Now when the day comes that I spot a box mod I can't live without, you can bet I will be throwing my money at it, lol.
Many will say mechs just aren't safe, I find that untrue, people are not safe. People will laud about how they have blown up and no one should use them. Now there are some people that shouldn't use them but some people shouldn't be allowed to drive either, yet they some how got a license. A mech. mod isn't a toy and it isn't for the lazy, if you aren't up to double and triple checking your builds or setups, then you should stay away from them.
The only mechs I have issues with are hybrids, there are too many toppers out there that are incompatible. If you know what can and can't work with them, you're good but many don't understand. Then there are the people that love their hybrid and love a certain topper but know they don't play well together and push the envelope. I don't want to see anyone hurt but it's their stuff and their face, but when the boom happens they blame the evil
device. I have yet to see one person that had a failure admit it was their own stupidity. I'm not saying they are stupid people but they made a dumb move, intentionally or not. If it was intentional, well there ya go and if not, well again there ya go.
People have to do their own research and not rely on someone's word. I get if you don't know ask and I support that but I also support what President Ronald Reagan once said "trust but verify". Never take someone's word at face value, take what they say and build off it. Get online research, take the time to learn all you can. In the end after hours of reading and running the math, you will soon learn whom to never listen to, you will see there is a type.
Get the mod you are most comfortable with and understand. Make a list of the mods you are looking at and look for what you don't like about each one, never look at what you do like first. If you look at the pros first, you will be blinded to the cons. If in the end if you have found a mod that you constantly come back to, it's probably the best choice. Best of luck to you, too many goodies out there to decide, I for one love it.
