The mod in question was of course the Pico Squeeze, which to this day remains as one of the most popular squonking options on the market. It's done extremely well due to its budget price, small form factor, durability and performance.
The Pico Squeeze 2 will shortly hit the market, and Eleaf have gone all out overhauling the design completely! The biggest change is that the Pico Squeeze 2 is now a fully regulated squonker, with adjustable wattage up to a 100W maximum, and temperature control support is now found on the device too.
A single 20700 battery is used to power the Pico Squeeze 2 with an adaptor included for 18650 batteries. There is a shiny new knurled metal battery cap located at the top of the Squeeze 2. A newly designed 7ml silicone squonking bottle is used, and Eleaf have also redesigned the feed system.
In the looks department, the Pico Squeeze 2 almost bears no resemblance to its predecessor, being much larger and having stainless steel elements to the design. The power button has been shifted to the side of the device, with a screen and plus/minus buttons on the opposite side, and overall the Pico Squeeze 2 looks a fair bit larger than the original!
Eleaf have also overhauled the design of the Coral RDA, which will now have a wide bore resin drip tip. The airflow and build deck have both been improved upon, to produce much better flavour and vapour!
I still use a Pico Squeeze to this day nearly two years after first getting one, and it still remains one of my all time favourite squonkers. I'll be interested to see how the Pico Squeeze 2 fares in comparison, and of course a full review will be on POTV in due course!
