I just received a Tmax V5 in the mail from Movapes for $25 and I thought I'd go ahead and share my thoughts on it. This was mostly an "impulse buy" based on the low price, and certainly wasn't the result of any
reviews I may have read (which I didn't). I've been curious regarding box mods so I thought this would be a good one to start out with for the price.
First of all, it came as a full kit which blew me away for that price. I thought I was only going to get the body itself. It came with two blue and white "Sigelei" branded batteries (1x 18650 2200mAh and 1x 18350 900mAh) as well as a "Sigelei" single battery charger (model: MTLC-0420-1000) that I don't have plans on using over my Nitecore i2.
The next thing that jumped out at me was that the Tmax felt very heavy when compared to my Zmax. I broke out my scale so I could weigh each of them without a topper or any battery inserted to find out what the actual difference was.
Zmax V5: 3.7 ounces (106 grams)
Tmax V5: 7.8 ounces (222 grams)
As you can see, it's just a hair more than twice as heavy, and you can definitely feel that when you hold it.
There are two threaded battery caps on the bottom, each for a different length battery. You can only use 1 battery at a time and only one size or the other (18650 or 18350). One of the 2 battery caps is rubber insulated and does not have a spring which I assume allows you to store a spare battery in the opposite bay if you want to and keeps you from attempting to use 2 batteries at the same time. The battery caps are thin and not easy to get a grip on with your fingertips which I found to be a little frustrating when compared to the ease of swapping batteries with the Zmax.
As far as the menu, I expected it to be identical to the Zmax V5 menu, but I was way off. First of all, the screen is square instead of being rectangular like on the Zmax. It's also seems to be slightly larger which allows the text to be a little bigger on the screen. Firing the button shows 3 lines of info vs the 2 lines on the Zmax V5. I'm taking into account that the Zmax V5 screen is longer and thinner while the Tmax V5 screen is shorter but taller.
Pressing the button 3 times gets you into the menu, but instead of getting to consecutive menu screens by pressing the button, all the menu "titles" are scrolled on the same screen (3 can be seen at the same time). The current menu is highlighted and if you continue to press the button, the "highlight" is scrolled down to the last menu item which is "Exit". If you leave the current item highlighted for a second or two, it will enter that menu and you can change options by pressing the button as you'd expect to.
While
vaping (after I set mine up to the desired settings of RMS and wattage), the 1st row shows "rms 8.0W", the 2nd row shows "res 2.5 ohms" (ohm symbol is used instead of the full word), and the 3rd row shows a battery icon colored in white to show charge level followed by a percentage of charge (ex. "85%"). If I want to know the actual voltage measurement of my batteries, I'm out of luck. There are no options to decide what is displayed on the screen when firing, such as found in the Zmax V5 menu (ex. Voltage, Resistance, Current, etc.). For example, you can't decide between voltage/power or your atomizer current. The menu always shows your voltage/power setting and atomizer resistance which is nice, but you don't have any choice in the matter. You also don't get a puff counter or timer, but those options are not important to me. I do however miss being able to see what specific voltage my battery level is as well as occasionally seeing what current my atomizer is pulling.
In summary, I can't complain about the price I got this Tmax for and it was nice that it came with a full kit which I didn't expect for that price. I'm not happy about how heavy and awkward it feels in my hand when compared to the Zmax. I mostly blame this on the fact that I've never owned any sort of box mod before, but I don't think I could ever prefer a box mod over a tube mod. It may have a lot to do with what you start out with and get used to. People who start out with box mods may find that using a tube mod is too strange to get used to.
I'm not crazy about the Tmax V5 menu since it doesn't allow for the same flexibility and fails to show you some of the info I'm used to seeing on the Zmax V5. However overall it's not horrible if you can get used to a battery icon/percentage (no specific battery voltage) and since it always shows your power/voltage and resistance. It was recently mentioned here that the 510 connector is not stainless steel and I'm certainly not happy about that. If I ever use this mod, it will likely be next to the sofa when I watch TV and it's definitely not going out the door with me anywhere. More than likely it will stay in the box it came in or possibly be given to someone I know who is just starting out on
vaping.
