I roped solo El Cap with this.
Totem cams are one of the 4 best innovations in aid climbing in the last 20 years. Highly recommended!
Can I put 6 stars
This is simply the best cams available in the industry. Why? Because of the design that applies an equalized load onto each lobe. That's why Totem cams are also a lot better on flare crack than most cams. The holding power is simply the best. Others cams have one stem with 4 lobes. Totem is 4 wires with 4 lobes. Each totem cams is mostly 2 cams of 2 lobes each equalized by a sling. When belayer said that you should put 2 protections close together, it's what you did each time you put a single totem cam. You can also load only 2 lobes. This tiny placement makes the cam the best for aid climbing. Totem cams are the more flexible cams make it very good in a horizontal placement. They don't walk as other. They fit where no other cams fit. The apply force is the same no matter how the cam is open or close. Others cam are more strength half close and decrease when the cams open. When the crack is flare all lobes will not be perfectly balanced except the Totem. It will always be perfectly balanced 25% on each 4 lobes. It's the best cam for marginal plecement, even wet and maybe icy crack. What you learn when building an anchor is it should be equalized. Totem cam is the only cam that will be always perfectly equalized and the wires and sling paterne make it redundant. The head of the Totem is so much narrow. It can fit in a small pocket where other cams of the same size range will not. It's more narrow because the springs of the totem are on the wires not beside the lobes. Even the X4 that BD describes like this: ''The X4's embedded cam springs allow for an ultra-narrow head width that fits in those tight spots other cams won't.'' is wider than the Totem of the same size range. One of the main advantages of the BD C3 size 1 and 2 it's the super narrow head but it's only 3 lobes. With the Totem cam, you have the same wide but made with 4 lobes. What should I say more? Also, the Totem is longer than all other cams except those with a double sling when is extended like DMM Dragons or New WC Friends. Longer cams are less prone to walk and does not need quickdraws as shorter cams. Totem allows 3 positions to clip the biner if a rock is in the way or might open the gate. So you can move the biner where it's the best. For aid climbing, you can also clip the cams high. The downside of the Totem is it rack on the wide side so it's bulkier on the harness but this minus is nothing compare to the benefits of the cam. This cam is 6 stars out of 5. It's simply above all others, period.
Really flexible cams
Really flexible cams and a great size for horizontal placements. I like the fact that the cams can be clipped in several different places along with the ability to place only have the came in a very shallow crack.

Most versatile cams
These cams are a true advance in engineering, the ability to place them in non perfect parallel's not only makes them more versatile but also much safer to place. A must have for climbers looking to start traditional climbing and a true upgrade for the more experienced!
the cam of the futur
From top to bottom, the best cam on the market, it make all the other cam look like python from the 50s. In 10 years, the c4 is going to be a prehistoric cam
