All-In-One Device and Nic-Salts

Due to the impending demise of the Disposable (and the excessive cost) the industry has come up with the device, which looks like a disposable but adds a bottle, or bottles of Nicotine Salt E-liquid (which is exactly the same as you get in a disposable). Some of these last for up to 10,000 Puffs without charging and this seems to be the way the market is going hence the dedicated Category. One of the advantages is that you can use your favourite liquid in any of these if you choose to. See what you think.
