The Hydro Tube from HVT is a great accessory for the Sai, but it definitely made my setup top-heavy and it was only a matter of time until a bump shattered it on my desk. What better way to fix this than by getting the world's most powerful and heaviest box mod, the 400W (with firmware update) quad-18650 Wismec Reuleaux RX300? I can confirm that my setup is now firmly anchored to my desk and will not tip. I'm expecting the batteries to last me about a week between charges at 10-15W. Now I just need Vic to hook me up with some quad Kanthal wax coils so I can start cloud chasing ;)

Here's another pic of my setup with the RX300 next to the eVic VTwo Mini mod I was using before. Notice how small the footprint of the old mod is by comparison! No wonder it tipped over all the time.

Here's a pic of my TiSai with Tesla Stealth TC40, the new RX300 with Sai and Hydro Tube, and the old VTwo Mini mod.

(Sorry for the water spots in the photos, I swear I cleaned up first!)

If you're interested in the RX300 watch DJLsb's video review here, it's very detailed and seems to give a fair overview of the mod's technical shortcomings. The 510 connection seems to be a major upgrade over previous Wismec devices which were flaky, but it doesn't do proper balanced charging/discharging so you should not drain the batteries too near to empty or charge them too close to full in the mod. You really need a good external charger for this, something powerful or you'll be leaving them on the charger overnight.

I picked up my RX300 from VapeNW along with 4 x Sony VTC6 batteries. They kinda gouged on the batteries but shipping was free and so it ended up being a reasonable deal, and they shipped VERY promptly.

In the pics is a Black Silicone Protective Wrap Sleeve for Wismec RX300 by ModSkins, $9.95 on Amazon, recommended both for protection and to reduce the risk of it slipping out of your hand.
