The REO Grand Series is no longer just a bottom feeder. The Reo Grand LP Version has a wide catch cup that will fit about any standard tank or dripper on the market. So one could buy the REO Grand LP for dual use. Bottom Feeder and/or Regular Mechanical Top Feed.. The Voltage resistance has improved to levels equivalent to the Tube Rockets.

The Reo Grand Line of Mechanical Mods have recently seen some changes and it's a game changer. The New Reo Grand is way improved over the Old one. I know because I bought one 7 months back and returned it. High Voltage Drop along with a Melting Button soured me on the REO. I'm no fanboy of any manufacturer, I just tell it as I see it.

The Manufacturer REOs Mods has upgraded the insides with low resistance materials and the resistance is comparable or better than most of the tube rockets on the market.

The advantage of the REO Grand is the following:
1. All metal and durable
2. Complete replacement kits are available for $25.00 that allow you to repair or gut your Reo Grand and turn it back to brand new.
Imagine every 1 year or so just replacing everything and having a new unit. This is attractive to me. BTW I'm very mechanically inept and I could rebuild this without a problem. You just need a screwdriver and the ability to watch a video and follow the instructions.
3. Because of Box Shape the unit is more stable when you put it down and less likely to fall
4. It's very small and compact
5. Rock Solid Reliability- It's one hundred percent mechanical and not much to go wrong
6.Price: the bottom end will cost $146.00, a Low Profile will cost $156.00, and a Sl Super Light $175.00. The SL LP is at $175.00 too. Compared to the High End Tube Rockets, the price is attractive.

If you choose certain versions of the Reo Grand than you get further features

1. If you choose a Low Profile - LP then you can use with just about any RBA. Not limited to Smaller RBA. Not limited to Bottom Feeding RBA either. You can use your standard Tank or Dripper.
2. If you choose a SL [Super Light] Version then there is a web of holes through the unit. I've found that the heat is absorbed by the body and then vented out through the holes. Result is that even under intense High Ohm vaping the body doesn't get hot. The temperature dispersion on my SL has beat hands down any tube rocket that I've ever owned. Some I've had to stop vaping because the whole body became warm.
3. They offer a Tumbled Aluminum Version of both the regular and the LP at no additional cost. Tumbled aluminum means no paint to scratch. I love it because it's virtually indestructible. By the way the pictures on the site of the tumbled version the finish looks much rougher then the REo I received.
4. Don't Drip and Drive- With Bottom feeding you get the dripping experience without the hassle of dripping. Safe for driving too

Now let's go into Negatives or suggestions for improvement.
1. You may not like the Boxy Shape
2. The hose arrived with the bottom totally flat, so if it hits the bottom it stops the suction of liquid. Quickly fixed by taking a scissors and snipping at an angle. It still would be considerate if it came that way.
3. It costs over the $100.00 sweet spot.
4. The APV is built to tight tolerances, it fits a standard 18mm battery, but I believe that the newer 3000mah batteries that are 18.3mm may not fit. So you are limited to a 2900mah battery
5. It's a Mechanical, if you like VV then this isn't going to be your cup of tea


Let's get down to the numbers:
I found the V-Drop to be good for my needs, in fact I switched from my .28Ohm to a .39Ohm Coil because it was too hot.

I have pictures of my results and equipment used in this post

While I don't have a reo, I do plan to get one as my next purchase and I like this new info that you're giving me. But what is this nonsense about the "new feature" of the newer reos being able to fit "any rda or RBA not just bigger ones"? I mean, it's a 510 connection, and it's always been a 510 connection, so why wouldn't it fit every 510 atomizer? Maybe I'm just misunderstanding, but that doesn't seem like any sort of new feature?

In any case, you just made me want one more.

I'm sorry if I'm not clear. Each REO has a Catch cup. The regular REO has a Catch Cup that is approximately 15mm and fine for the smaller RBA like the A7 or the Reomizer 2. If you put a large RBA on it then the Male 510 connector wouldn't reach and you'd need an 510-510 extender to allow it to screw in , also the RBA wouldn't be flush with the APV.

The LP or Low Profile has a shallower and wider Catchcup that will accommodate most of the RBA on the Market. I'm not sure the width but I'll find out. The result is that the limitation of only using small RBA has been removed on the LP model.

Net result is that one could use there favorite Tank , or Dripper on the LP model and just not take advantage of bottom feeding.

Below is a picture of mine which is the Sl but not the LP Version.

That's still a pretty big voltage drop and the price is a gigantic turn off, but the convenience is great.
There is a lot of misinformation about V-Drop. The V-Drop on mine takes into account, resistance of the Battery, the Rba, I've seen some charts out there that use a hypothetical testing method and is innacurate.

I went into a Vape Shop last night and tested the Mechanicals that the workers were using and in all cases in real world results the tube rockets were giving results below what I've tested.

The only two methods of accurately testing v-drop is to use a multimeter [Attach prongs to each end of the Posts] while firing or to get a voltage indicator.
Mad Vapes sells one very reasonably.

You should check and remove the battery sag. Do that by having your probes on the battery ends and fire. The drop you get there is from the battery. Minus that drop from your original drop and you get the real drop from the mod.

Good Idea but
In my opinion this would just confuse the public. I like to keep it simple.

Great review Tom. I have an LP Reo Grand on the way actually. I love liquid feed - but I like that I will be able to use a range of toppers. So it can be used like a regular box mod or as a bottom feeder. Mostly it will be bottom feed for me.

Unlike you I don't go sub-ohm but I will do some coil builds with it. :) Thinking of adding a kick although a lot of people don't bother and just coil build instead. Anyway - good stuff. Thanks.

glad you're happy with the changes Rob made to the device. I love my Reos & don't have any interest in anything else at this point. I also agree with you that it's awesome to be able to get the repair kits for them & fix everything so it's as good as new. I also love the Rob cares whether or not his products work for people & how well they work. If he didn't care he'd have never bothered with the sub ohm upgrades since plenty of people were buying the Reos without the upgrades. They're just good devices. Glad you're happy with yours. :)
