Boundless Terp Pen Review – Terpin in the USA

Updated: March 26, 2024

We’ve checked out a lot of devices by Boundless before, like in our Boundless CFV review and Boundless CFX. The new Boundless Terp pen is the successor to the Boundless CF-710. Three times smaller, equally lighter, and supposedly powerful as the original, we were very keen to review it. Is the Boundless Terp pen any good? Check out our review of it here for more!

Review: Boundless Terp Pen

Boundless Terp Pen Review

Boundless Terp Pen heating coils

How it Works

The Terp just like the Linx Ares works somewhat like a nectar collector. On one end is the ceramic atomizer which heats up and should be applied directly to your concentrates while inhaling. It has a sensor to automatically detect an inhale for nearly seamless use. The magnetic cap quickly pops on and off to protect the coil from any possible damage.

You can either use the Terp just like a nectar collector or pre-load it for a session later – just melt some wax onto the coil and inhale from it later for a session at any point!

Temperature Flexibility

Sadly, there is no power control. The longer you inhale, however, the hotter the coil will get. It’ll heat up within a couple of seconds and cool down quite quickly as well.

A crude form of power control would be by modulating your inhales and such, manually activating and deactivating the heater. This may take a little bit of effort and learning however good results can be achieved.

We would have preferred to see ranges closer to what we experienced with the Utillian 5 (V3), which gave us 4 voltages to choose from for some seriously tasty or massively cloudy rips.

Vapor Quality

Does it ever hit like a truck! Wax pen vapes nowadays are pretty potent and even the most basic ones can leave you wheezing for air from monster hits. The Terp follows that trend, though the vapor is actually quite a bit better than others for one simple reason; the vapor path.

At the air must travel the distance of the pen from one end to another, the vapor is drastically cooler than if the heating element were right near your lips. This leads to much smoother, cooler, and nicely flavored vapor.

Depending on your material and draw technique used, you can achieve light, wispy yet flavorful hits or monster draws that’ll practically leave you asthmatic. Certainly, the Terp works much better with small loads than large, we recommend only going for a maximum of a rice grain sized amount to have the Terp working the best.

However, when it comes to nectar collectors we still tend to prefer the Linx Ares, which doesn’t have any exposed coils for much better flavor and longer coil life.

Manufacturing Quality

It’s a simple little device with not much to it. Boundless has a pretty good reputation for their build quality, albeit a bit cheap with many of their devices being mostly plastic. The Terp is instead metallic like the Linx Hypnos Zero and feels great in the hand, they may have taken a nod from fellow wax pen maker Linx. Comfortable, classy, and well machined, we have no problems with how the Terp is made.

Included in the box are the internal battery, outer body shell, replaceable ceramic coil, mouthpiece, protective metal cap, USB charger, and quick start guide. This is par for the course and we would’ve liked to see a spare coil included in case the included one inevitably dies.

Battery Life

At 300mAh, the internal battery is fine. With such a small unit you really can’t expect anything crazy, and realistically we say you can expect between 30-45 decent hits before needing to top up.

This is fine for multiple days of use or maybe a group session, but expect to top up the battery more frequently if you take multiple hits throughout the day or go for extended outings. Frequent users, however, prefer units like the Source Orb 4 Premium Kit that aside from having good battery life, it’s also removable – a blessing in disguise for the ones constantly moving throughout the day.

Boundless Terp Pen portability

Portability

This thing is smaller than the infamous Grasshopper vaporizer. Barely larger and heavier than your average ballpoint pen, this thing is seriously impressive and can be taken practically anywhere.

Very easy to slide into your pocket to forget about later and pull out for a quick session.

Ease of Use

Draw to inhale devices are incredibly easy to use and simple. Though you can really master the draw technique to play with the coil to get your favorite results, tossing it off to a friend or stranger for a quick hit or two will require almost no instruction – just inhale! No need to even take the cap off!

The entire unit disassembles pretty nicely too like the Utillian 2 Wax Pen, making cleaning a lot easier than most. Simply submerge the parts in isopropyl alcohol (not the battery) or use a small cotton swab dipped in iso to scrub away at any build-up and grime.

Discreetness

Barely the size of a pen, it’s super easy to conceal and some people may even mistake it as a pen unlike some portables like the Puffco Peak that are a big larger in size. Don’t rely on that though! Since it has near-instant draw to activate, a quick power session could be had in mere seconds. Pull it out, take a draw, and you’re done! Simple as that.

Overall Experience

For the suggested retail price, you really can’t go wrong with the Terp pen. It’s tiny, affordable, works well, and is great to just throw in a bag or your pocket for ‘emergency’ sessions. It’s built well, and Boundless certainly has a good reputation among the community now.

As for the Boundless Terp Pen coils, you can reasonably expect to replace it every couple of months or so, which is about average for these wax pen devices. It all disassembles nicely, cleans well, and hits quite well! Not the greatest for heavy users and those with high tolerances, but the average user will certainly be more than satisfied!

We still think the Ares offers better flavor and prefer the coil-less nature of the Linx product line and if you want to get away from the nectar collector style check out the Utillian 5 (V3) wax pen, an absolute powerhouse that will challenge even your favorite rig.
