The T5 is a large device it has a diameter of 37mm and a 110mm length I find  it odd that they only managed to fit 1 18650 inside the casing.
The T5 display is bright and clear you get information about the resistance of your coil, the voltage the device is firing at to produce the wattage set and a battery display which is in percentage and a sun dial. The battery display on the T5 is a weak point it does not read accurate it goes down stupidly fast then still vapes when showing 0% the firmware upgrade was meant to sort this problem.
The Cloupor T5 (http://www.cigabuy.com/cloupor-t5-50w-18650-tube-apv-mod-p-6217.html ) has up and down buttons below the display for setting the required wattage. The resistance measurement is accurate and it is stable so the T5 produces the same vape every fire which is a good point.
The T5 does vape well but at the same time it has it’s problems. Clouper made big statements when selling this unit about the firmware being upgradeable just look at their website it listed as one of the main features of the T5. It has annoyed me a little that they are no longer plan to release a new firmware I would like them to still be working on a small update to improve the battery display and the problem with the device turning it’s self off every so often. I am not concerned with getting increased power and a changeable boot screen but I would like the device to run correctly.
The vape which the T5 delivers is dexcellent but it is a large device to only contain a single 18650 battery overall I do like the T5 it’s a lot better than my IPV2 for reason’s expained earlier in this review but my ZNA30 is better it’s a lot smaller and with an 18650 battery tube a full charge last about the same time in both devices at the same power. If you really must have 50 watts or more I would wait for my reviews coming up on the GI2 or ZNA50 or look elsewhere at the Cloupor T6 or Cloupor T8 from Cloupor I notice they are not adverttising them as having upgradable firmware.
