In popular European and American film and television dramas such as "House of Cards", Blu can often be seen. Blu was originally an independent e-cigarette brand, began to sell e-cigarettes in 2008, and was acquired by the third largest tobacco company in the United States in April 2012 - Lore Lard, for $135 million, with the strong strength of the parent company, Blu in the sales channels and marketing strategy at the same time, its distribution stores from the initial 10,000 rapidly expanded to 136,000, once became the best-selling e-cigarette brand in the United States.
 
Despite its success in Blu e-cigarettes, Loreillard is still under pressure to survive, and in July 2014, Renault agreed to buy Loreillard for $27.4 billion. Since Renault already has the Vuse e-cigarette brand and has invested heavily in the Vuse brand, in order to avoid violating the anti-monopoly law and alleviate the financial pressure on Renault, Renault's acquisition does not involve the Blu e-cigarette brand, that is, when Loreillard is acquired by Renault, Blu will be sold to Imperial Tobacco.
 
For Imperial Tobacco, the three-way merger has increased its market share in the U.S. tobacco market from 3% to 10%, making it the third largest company in the U.S. tobacco market. With the brand support of Imperial Tobacco, Blu has also been performing well, according to data released by Nielsen, since 2015, Blu e-cigarette sales have been among the top four in the United States.
 
According to a 2015 study (PMC search ID: PMC4323666), the average copper content in Blu e-cigarette smoke is 6.1 times that of traditional cigarette smoke, which has become the main basis for external attacks on e-cigarettes.
 
However, in the study of chemical hazards such as acetaldehyde and propionaldehyde, Blu e-cigarettes are much less harmful than traditional cigarettes. For example, the consensus research report (Public Health Consequences of E-Cigarettes) published by the National Academy of Sciences, Engineering and Medical Sciences of the United States in 2018 pointed out that the content of acrolein, acetaldehyde and propionaldehyde in traditional cigarette smoke is 86-544 times that of Blu e-cigarette smoke. Public Health England also pointed out in its published study that, overall, e-cigarettes are up to 95% less harmful than traditional cigarettes.
 
Blu's product line includes disposable cartridge e-cigarettes and refillable e-liquid e-cigarettes, and its products include blue PLUS, blue PRO, blue ACE, and my blue. Among them, blue ACE and blue PRO are refillable e-cigarette e-cigarettes, compared with pre-filled e-cigarettes, oil-filled e-cigarettes need to inject e-liquid into the atomizer before use, and the atomizer is also a consumable, in order to maintain the consistency of taste, it needs to be replaced frequently, which is not as convenient as the pre-filled e-cigarette.
 
BLU Plus and My BLU are pre-filled disposable cartridge e-cigarettes, My Blu is priced at 10 euros, while BLU Plus comes in Slide and Charge bundles for 15 and 30 euros respectively. The Slide is a regular set, and the Charge set comes with a rechargeable cigarette case, which can be used to charge the stem when it is low on power, and can also hold 2 cigarette sticks and 4 pods. The blue Plus is connected to the cartridge by a screw, the stem has a simple and beautiful black shape, and the iconic bluee LED lights up at the bottom when smoking, in addition to the decorative function, the bluee LED light can also indicate the remaining power of the cigarette stick, and the continuous flashing means that the stem is low on power and needs to be recharged.
 
In order to seize market share with JUUL, Blu also launched my blue (pod mod type) e-cigarette product in 2018, which still maintains a high level of production, with a stylish appearance and a small and portable size, my blue is equipped with a 350mAh battery, which can fully charge the main unit in about 25 minutes. In terms of experience, My Blu has a large amount of smoke and a suction resistance close to that of real cigarettes, making it a good choice for users who have just transitioned from traditional cigarettes.
 
My Blu currently offers 16 flavoured pods in tobacco, fruit, beverages and mint, priced at £6 each. According to the evaluation of Electronic Cigarettes Reviews.net, most of Blu's e-cigarette flavors are sweet and more in line with women's tastes.
