received my units on Friday (TV I sent you an email with regards to freight details if you could please reply), There are a lot of user variables with this device so some details may help buyers/future buyers with getting the most out of it.
With the delrin sleeves, they spin freely on the heater section on my units as with all from the sounds of it. When screwing sections together if no force is used and you only gently do them up until the point that they do not go any further and do not use any force to torque them together, you will find it easy to pull sections apart to replace batteries and load even when hot.
Now to use.
I tried this out a few times before even reading the instructions, I wasn't happy with vapor production after allowing it to heat up for 5-10 seconds so I let it warm up for longer periods first (20-30 seconds), this is not a good idea and results in some combustion and reduced battery life per cycle. It only takes 5-10 seconds for the element to reach required temps then relies on air flow (users draw) to transfer heat from the element to the herb allowing the herb to get to vaporizing temp. So allow the unit to pre-heat for 5-10 seconds then draw slowly until you can taste vapor/feel it in the back of your throat, then slow increase rate of inhalation for the duration of your hit. This can take some practice to get right, but once you get the hang of things, thick tasty combustion free clouds are easily achieved, leaving the unit to heat longer then suggested only introduces more conduction heating and reduces number of hits per battery change out.
Stirring
This is essential to getting as much as you can from your herb and leaving your abv an even color. I have found the easiest way to do this is to simply unscrew the cap most of the way (unscrew completely then screw back on between a quarter to a half turns), hold the heater section and cap together between thumb and finger, then shake. After a quick shake screw the cap back down to it's closed position while holding the device upright, as the inner disc inside the cap seals down ontop of the bowl when screwed together this ensures the herb is packed back down into the bowl. I do this between every hit and am getting around 10 decent cloudy hits to a load/battery change with perfectly even brown abv.
Before using this method I tried as others suggested with tipping it into my hand, breaking it up a bit and returning to the bowl, I would not suggest this myself as some partials seem to fall into the heater section and introduces the combustion taste.
Grind and Load size
For myself I find it best to use a single grind through a 4 piece grinder, then fill the bowl completely but without packing it down at all. The courser grind eliminates the problem of combustion of finer partials and the filling method allows the above mentioned stirring/shaking method to work well.
Taste
For the last 6-8 months my main vape has been an LSV used with a water pipe, anyone with experience using this setup would realize I have been spoilt as far as taste goes, nothing comes close to an all glass setup for flavor, using an ssv or eq direct or through water just doesn't come close due to the silicone tubing.
When I decided to try the TV I felt due to it's design (not glass) I would be compromising on flavor. My thoughts were I would be willing to do this for a portable, The pure clean taste provided by the LSV is now a must for me when it comes to a home vape, but for a portable durability, speed of use and stealth design are higher on the list, compromising on taste for these sections wasn't an issue for me.
My first impression of the taste of vapor produce from the TV were similar to that of the Iolite, nothing impressive but satisfactory for a portable. After learning how to use it properly I cleaned the mouth piece and now the flavor is for me on par with all glass designs. I don't know if initial poor quality in flavor is a result of the device needing a clean before use or as a result from my initial misuse of the TV, either way if you are not getting the cleanest tasting vape from it clean the top cap section and mouth piece.
Water Pipe Use
Using the long mouth piece provided, cut a 1/4" piece of whip tubing and push it on flush with the end of the mouth piece, this will allow it to seal in a 14mm glass downpipe without introducing the silicone tube used to the vapor path. This only works with the long mouth piece, the shorter one does not extend long enough to create a seal, you could use a longer piece of silicone tube but this will then be introduced to the vapor path and effect taste. I tried this after cleaning the cap and mouth piece as mentioned above, the flavor was on par with my LSV, I could not pick the difference and would be surprised if anyone else could. Cloud production is on par with my old EQ, but not as thick as the LSV, I'd say given the heat up time required and the design of the TV it really did exceed expectations in this area. I seem to be using the TV with my water pipe when I just want one or two quick hits, or sometimes for a couple of hits while waiting for the LSV to get to temp, a power supply would be a great idea for this type of use.
Heat
A few people have mentioned this as a bit of an issue with the battery slide getting quite hot to the touch, I also found this to be the case at first when using the TV incorrectly. Once working out required heat up times and draw technique I have found the radiant heat of the unit to be less of an issue. For myself there is a 20-30 second pause between hits while I hold in the previous hit and give the TV a stir/shake, with this short pause between hits the device doesn't get too hot to use. If you are finding the battery slide is getting too hot to use, you need to work on your technique, possibly reduce pre-heat time and adjust inhalation method, it only takes one inhalation to get nice a nice cloudy lungful, if you are taking a first lungful and getting nothing then taking another directly after to get visible vapor it will reduce hits per battery charge and increase radiant heat.
Over all I am quite happy with the purchase of the TV, or at least will be once an issue relating to freight cost and method on my order are resolved, I will provide further details on this once I hear back from Thermovape as how it is handled will determine if there was an honest mistake or a dishonest company. If you want a personal vaporizer that can be easily taken anywhere, tastes fantastic, durable and discreet, this is where you want to look, if you want something that is suited to use with multiple people, more cordless then truly portable, then there are probably other options more suited. But again, for a true portable vaporizer I couldn't recommend any other on the market over the TV.
I would like to see a power supply option (if not will make my own) But the idea of a usb supply doesn't sound ideal. USB 2.0 has an output of less then 5 watts, if this were to be utilized as a supply for the heater, technique and use would be very different to when used with the batteries. I would rather see a 110-240vac primary - 6vdc 5amp secondary power supply with use of a button (or slide) to provide power to the heater only while in use.
