First of all the conversation when choosing an ecig should always begin and almost end with the MODEL - not the brand.
The BLU is a bad choice for 2 primary reasons.
1. It is a low end model of ecig.
2. It is grossly overpriced.
It is also bad if you smoke a lot, etc. as those type of models do not last nor have adequate performance.
Use this same exact reasoning with the SmokeStik (a 4081) or Value4Life (KR808D-1), etc. They are primarily brands with "some" differences.
First of all when choosing an Ecig, avoid the E8's, the E9's, the L88's, etc. They are a waste of money. Period.
Regardless of what you value in an ecig (size is the ONLY reason to even look at something like that) there are simply better options that are less expensive.
Whether you choose a 501, 4081, EGO, whatever....The logic still applies. For instance, you can buy an EGO "type" that is not made by JOYE and this is the RIVA. Some want genuine JOYE, some do not care.
Point being, every "brand" is a type of model of ecig. Understand the model FIRST and what you like about it and THEN choose a brand. Most new users do not understand models and why they get confused by all this in trying to make a decision - and ultimately buy the wrong one for them.
