Utillian 721 vaporizer review - An affordable convection herb vaporizer

Utillian 721 vaporizer review

The Utillian 721 is the second device we tested from this particular Chinese company and we have to say we are more than impressed. It’s a rock solid portable dry herb vaporizer which can compete with most of the top industry leaders. The body is made from anodized aluminum and uses convection heating inside the top placed chamber.

Vapor tends to be quite harsh at highest temperature setting

Why is convection heating such a big deal?

Convection heating is something we used to see only in high end dry herb personal vaporizers. This technology is expensive to implement because it doesn't work like the more affordable conduction solution and uses an entirely different principle. If in the case of conduction the chamber walls are heated up to a certain temperature, convection uses a stream of hot air that passes through the weed vaporizer. This ensures an even distribution of heat and even vaporization, without the risk of partial combustion. It accounts for clean, smooth flavor and a very satisfying overall experience.

What you get in the Utillian 721 box

Inside the cardboard presentation box you will find the Utillian 721 vaporizer itself. You also get the user manual, a pair of tweezers, a wax/concentrates canister, a cleaning brush and micro-USB cable. When it comes to spare parts we have an extra mouthpiece system as well as spare screens and O-rings.

Utillian vape: design and features

Just like it's smaller brother, the Utillian 420, the Utillian 721 vaporizer has a simple and efficient design. It fits the palm of your hand just perfectly and can even be stealthy at times. The top cap includes a rotating mouthpiece, which is very similar to that of the Crafty.

The cap is held in place by a very strong magnet and when you take it off you have free access to the heating chamber. This device is operated with a single button and the micro-USB slot is placed on the bottom.

The rubberized finish on the anodized aluminum outer shell looks and feels top quality. It gives the device a high end vibe and seems to be quite durable in time. The mouthpiece while made of plastic doesn't give off that distinctive flavor and it’s actually very comfortable to use.

It has four different temperature settings and a super bright color changing LED notification on the top. Green is 170C, Blue is 180C, Purple is 190C and Red is 210C. All of these temperature settings have an extra boost mode which further enhances each value by an additional 5C.

The Utillian 721 vaporizer is powered by a 2100mAh battery, which will last for around 60 minutes of use at 180C. Heat up times is also very fast, the device being able to reach maximum temperature in little under a minute.

First use

To prepare the unit for first use, select the highest temperature setting and let it go through four cycles. The device will automatically shut itself off after each five minutes. This will get rid of any odors and sterilize the stainless steel chamber. Once the device has cooled down, remove the top cap and fill the oven with ground dry herb material. Make sure it’s loosely packed since this is essential with any convection vaporizer. Put the top cap back on, select your favorite temperature setting and wait for the vape to reach temperature. We recommend the first two temperature settings for beginners, as Purple and Red can give pretty harsh favor at times.

Utillian 721: Performance and conclusions

The Utillian 721 is the most affordable convection heating vaporizer we tried. It’s very well built, the materials are high quality and performance is outstanding. Flavor is clean and delicious and the mouthpiece while plastic, doesn't give off that characteristic aftertaste. Battery life is more than reasonable and heat up time is really fast. We didn't get the chance to test out the concentrates chamber but we promise to update this review in the future. The only con we found is the harsh vapor we got from the highest temperature setting.
