It sounds like a knock-off brand, so it probably won't perform with the 'best' results. You shouldn't be too bummed though. You did take the first step into ditching those cancer sticks! And thats what is important.
Now, you simply have to make those adjustments to finding what works best for you.
If you have some extra cash to spend, I would recommend picking up a Joye 510. That seems to be the most popular among new users (heck, I've been vaping for 7 months and its my go-to PV). Its a little bit wider and slightly longer than a 401 (if u do infact have a 401 knock off). You can find cheap starter kits on most of the registered suppliers. Litecigusa.net is good one that offers free shipping on orders 15 bucks or more. cignot.com is another good one.
If you are stuck on that specific model, then Id recomment getting a true 401. You can find them around as well. I got mine from truesmoker and I love it being my first PV.
Reguardless of what you decide to do, just remember some models that work for other users, might not always be the best for you. It'll take time to find your niche, but it'll be worth it! hope this helps.
