Infinity Pro Review
Note: I tend to be very critical in my review of anything, keep that perspective in mind as you read this review. Review is based upon about 5 weeks of use.
The Infinity Pro is a good contender in the variable voltage market largely due to its $99 price (w/o any accessories).
Form Factor
It is a long and slender mod rather than the shorter wider mods that predominate (4.75 x .72). It is incredibly light even with batteries. It is well suited to be used with a atomizer or carto without a tank. With a tank it looks very awkward; the tank hangs out there on the end of the narrow connector.
Fit and finish:
There are a number of color options: black, chrome, clear/silver, purple, and blue. It appears that the colors are anodized, the silver is clear over the aluminum metal. I had the chrome version which doesn't appear to have been anodized as I had problems with the finish not typical of an anodized finish.
I imagine that the anodized (colored) version may not have this problem, but the chrome finish developed a network of fine scratches just by being in my pocket for just over a month; that is with nothing else in my pocket. In fact they were so evenly patterned and developed so slowly that I convinced myself that they had always been there. So when I sold it as "like new", the buyer was understandably very upset and I took a large loss in the transaction.
I had the brass endcaps and they were perhaps the best component on the IP. They were precisely machined and had a slightly satin finish. The endcaps come in brass or chrome and with 510, 808, 901, or 801 connections. The batteries rattle around a little in the tube like many mods, but not under normal conditions (you have to shake the mod).
Function
The button is an extremely small red button and while I didn't particularly care for its size, it performed very well. It does look like it came out of an hobbyist electronics kit. It also has battery production built into the device.
The voltage dial steals the show. It has the right amount of resistance to be both easy to rotate and resistant to accidental (pocket) voltage changes. While there is no electrical display, it is made up for by the easy to adjust dial. I was able to find the right voltage for any carto/atomizer in about 20 seconds without ever needing to know that actual voltage.
The performance was just what you would expect from a variable voltage mod. It can adjusted it to give whatever performance you want. The maximum voltage is 5.5V which is enough to run all but the most highest resistance.
Once, after changing a carto I had a mysterious failure of the device that defied all attempts to remedy for 3 hours. During this time I changed out 4 different sets of batteries and a similar number of cartomizers. Suddenly it started working again, perhaps it was a connection problem.
Final evaluation
I sold mine, this was completely due to the shape of the Infinity. It looks idiotic with a large tank connected to it. With an atomizer, such as for direct dripping the slanted endcap looks great. The chrome finish didn't stand up to the most compassionate of handling, you may have better luck with the colored finishes. The dial for voltage works great, you do not need those digital displays. Other than scratches it appears to be a durable device and very light in weight at the same time.
