What's the greatest blocker right now? Too many orders for just one guy, or supplies / tools affected by coronavirus?
To secure a Tetra, I respectfully suggest that, after first emailing Lamart to notify him of your interest, you open an account at Lamart's website before the next drop, so you can immediately add a device to the cart when the devices are made available.
Next: go thru all the options available on the website before the next drop:
which device: the TetraX or the TetraP80?
custom or pre-built device?
which (custom) wood type?
which stem: straight, bent, dimpled, etc.?
if you use glassware, then choose an optional wpa: 18mm, carbed, etc,
if using the S&B dosing capsules, then order from the 3 types of optional wooden stems with optional glass & folded metal inserts.
how will you pay: Paypal or credit card?
Speak to your bank/credit card company well before you order so they will immediately approve the payment without delay. Some people have had issues with some banks that require extra approval.
The recommended Tetra mod is the very inexpensive Joyetech Cuboid 200w, which requires 3x18650. Lamart has an updated list of mods on his website, but generally Joyetechs & Wismecs. Lamart recommends the Samsung 30Q 18560 battery. Purchase 18650s at approved battery resellers, but never Amazon, never Ebay.
