Review Summary


The Core 2.1 eRig by Shenzhen Crossing is a solid performer, offering impressive vapor quality and robust battery life at an accessible price of $150. Its 3D atomizer, easy one-button operation, and durable design make it user-friendly. However, it falls slightly short in terms of precise temperature control and could benefit from a more secure carb cap design. Overall, the Core 2.1 stands as an excellent choice for both new and experienced users seeking quality without a high cost.


The Core 2.1 eRig, coming from Shenzhen Crossing, steps up from its older sibling, the Core 2.0, with some noticeable tweaks. It's clear they've been listening to feedback, as they've made changes like a non-rebuildable 3D atomizer and a beefier 3150mAh battery. These updates are more about refining the experience rather than overhauling it. Shenzhen Crossing isn't exactly a newcomer in this space, so it's no surprise they're tweaking things based on what users have said.

Core 2.1 first look on the design

As for the price, the Core 2.1 sits at $150, which is honestly pretty decent for what you're getting. And if you snag the TVG10 coupon code on vape-smart.com, it drops to $135. For an eRig with these features, that's not too shabby. It's not dirt cheap, but it's definitely on the more affordable side, especially considering some of the high-priced concentrate vaporizers out there, such as the Peak Pro. So, if you're looking to get into eRigs or want to upgrade without breaking the bank, the Core 2.1 seems like a solid bet. Check out the in-depth review below. 

Design & Features

The Core 2.1 has a sleek, no-nonsense design. The base feels sturdy in your hand and looks like it's built to last. The Borosilicate glass bubbler sits snugly on top and is obviously removable for cleaning. The connection between the glass and the base is pretty seamless and tight. 

The base is made from aluminum, and it has one activation button with an LED indicator around it. The front has a USB-C charging port, and the chamber, which we'll get to in a moment, is right above it.

3D Heating Element

The 3D atomizer in the Core 2.1 eRig is a notable feature, setting it apart in the eRig market. It's a ‘bowl' atomizer, crafted entirely from ceramic, which is a big plus for flavor purity.

What makes it ‘3D' is the arrangement of the heating wires. Unlike traditional atomizers that have heating elements just at the bottom, this one has wires embedded in the walls of the bowl too. 

This design ensures an even distribution of heat across the entire surface area. So, what you get is a consistently heated bowl that vaporizes your concentrates evenly, translating to a smooth and flavorful experience every time you use it. The even heating not only enhances the quality of each draw but also makes the most out of your concentrates, ensuring nothing goes to waste.

To put it in perspective, the Puffco Peak Pro, a well-known player in the field, also boasts a 3D chamber. However, it comes with a heftier price tag of around $420. In comparison, the Core 2.1 eRig's 3D atomizer offers similar advanced features but at a much more accessible price point. This makes the Core 2.1 an appealing option for those who want the cutting-edge technology of a 3D atomizer without splurging too much. It's a great example of how high-end features are becoming more available in the market without necessarily carrying a premium price.

How to use

Using the Core 2.1 eRig is quite straightforward, making it ideal for both beginners and seasoned users. To start, I recommend using a hot knife for loading your concentrates. The sticky nature of most waxes makes them tricky to handle, and a hot knife simplifies this process, allowing you to place the concentrate in the bowl precisely without any mess or wastage.

Once your concentrate is loaded:

  • Power Up and Select Temperature:
    • Turn on the eRig by quickly clicking the button five times.
    • Cycle through the four temperature settings by clicking the button three times. Each setting is indicated by a unique color.
    • The temperature ranges from about 205°C (401°F) to 260°C (500°F), offering options for different types of concentrates.
  • Heating and Usage:
    • After selecting the temperature, wait for the eRig to reach the set level indicated by the LED, and the unit vibrates. 
    • Once heated, it's ready for you to inhale and enjoy your session.
  • Post-Session Cleaning:
    • Use a cotton swab to gently clean any excess residue from the atomizer. I use these glob mops, which work great.
    • This step not only maintains the atomizer for optimal performance but also ensures the flavor remains pure for future sessions.

Performance & Vapor Quality

When it comes to performance and vapor quality, the Core 2.1 eRig packs a serious punch, especially considering its price point. Here's a breakdown of what stands out:

Vapor Quality

 The vapor quality of the Core 2.1 is surprisingly top-notch for its price range. It's easily one of the best you can get without splurging too much. The flavors come through clearly and the vapor feels smooth, making for an enjoyable experience.

While it holds its own remarkably well, it doesn't quite match the Puffco Peak Pro, mainly due to the latter's more precise temperature control. This isn't a dealbreaker by any means, but it's a point to consider if you're comparing the two.

Battery Performance

The battery life on the Core 2.1 is impressive. It lasts easily through a full day of use, which means less worrying about frequent recharges and more time enjoying your sessions. This long-lasting battery is a major plus for anyone who values convenience and reliability in their vaping experience.

Vapor Production

 If you're someone who enjoys thick, milky clouds, the Core 2.1 won't disappoint. It produces ample vapor, ensuring that each session is not only flavorful but also visually satisfying. This aspect of the Core 2.1 is particularly notable, adding to the overall appeal of the device.

What could have been better?

While the Core 2.1 eRig stands out in many aspects, there are a couple of areas where it could see some improvement:

  • Precise Temperature Control: One of the noticeable shortcomings of the Core 2.1 is its lack of precise temperature control. Although it offers a range of temperature settings, they are preset and not as finely tunable as some users might prefer. A more precise temperature control could enhance the device's appeal, especially for enthusiasts who are particular about hitting the perfect vaping temperatures for different strains and textures. But again, I'm nitpicking here because no device at this price level offers precise control. 
  • Carb Cap Design: Another area for potential enhancement is the carb cap design. Currently, the carb cap on the Core 2.1 simply sits on top of the atomizer without any pressure holding it in place, it just kinda sits on top of the atomizer. A carb cap that is held in place by pressure or a locking mechanism could provide a more consistent and efficient vaporizing process. 

    These aspects, while not deal-breakers, are worth considering for future upgrades. Fine-tuning these features could elevate the Core 2.1 from a great eRig to an exceptional one, aligning it even closer with the needs and preferences of a wider range of users.

    Bottom line

    In summary, the Core 2.1 eRig really shines in its performance and vapor quality. It's a device that impresses, balancing cost and quality in a way that's hard to beat. For anyone looking for a reliable, high-performing eRig that won't break the bank, the Core 2.1 is definitely worth considering. It delivers where it counts, offering a premium experience at a more accessible price and making it one of the best Electric Dab Rigs of 2024.
