It's a 30 day money back guarantee and 3 yr warranty on the swivel. If that's a good enough warranty for you buy it. If not, buy another brand.
ALL manufacturers have issues with their equipment if they wouldn't offer warranties.
PS:Matt Nichols a follower/lurker on TMF bought it. Perhaps he can do a follow up review.

Now I would like to pose a question about the "2" competing wands.
Each wand has two seals, front and back, in the head to prevent grit and debris from getting into the bearings with life expectancy of 3 to 5 years max. Which wand will you be able to disassemble to replace the seals without using a saws all?

Nice to have competition though. Remember the one the "other" board extols has a vested interest in the competing wand. He has been known to childishly berate anyone who disagrees with his narrow mindness.
Look at how he "judged" the Mytee T-Rex as garbage and Mytee does have some manufacturing issues but the TRex has been a solid winner for them. Lets not forget how he "magically" broke the TRex handle and said the whole unit was rubbish based off of that and fact. So would such a childish person pull the same prank with a wand to get their way?
So its best to take all the information and make a calculated decision on whats best for your business, business model, cleaning style and budget. Ultimately out is each Individuals choice to make an educated decision.

During the Second World War, inventors shifted their perspective to chemicals, which evolved into modern-day carpet cleaning and dramatics ensued. In fact, carpet cleaners still employ the same basic principles developed after 1945 in today’s industry while arguing over methods, procedures and equipment. Over the years, the carpet cleaning and flooring industry has improved its system and chemicals to clean more efficiently. However the basic principles and dramatics has remained the same if not intensified. Therefore as long as their will be carpet cleaners their will be dramatics.

As stated previously, most small bearings are used in applications where rotational accuracy and low torque are primary requirement and loads are light. Therefore the operating lifetime of the bearing is relatively long, and, if properly operated, failure is rare. Nevertheless, all bearings have a finite life under use and will eventually fail to perform satisfactorily due to an increase in noise and vibration, loss of running accuracy, deterioration of lubricant, or fatigue flaking of the rolling surfaces. Such failure modes are considered "normal" and can be predicted using standardized techniques.
In addition to normal deterioration, bearings may fail due to heat seizure, fracture, scoring of the rings and other conditions caused by improper use, selection or maintenance of the bearing. Such failures are not normal and can only be avoided by careful handling and correct operation of the bearing in a given application.

The following formulas permit the calculation of the fatigue life of bearings subjected to radial loads or combined radial and axial loads. Some of the formulas include approximations. Contact PACAMOR KUBAR BEARINGS Engineering Department if the calculated life is borderline in comparison to the desired life or if the loading conditions differ from those presented.
The Fatigue Life (synonymous with L10 and Rating Life) of the bearings is the number of hours or revolutions reached by 90% of a group of bearings subjected to the same loads before the onset of fatigue. Conversely, 10% of the same group of bearings can be expected to show evidence of fatigue before the L10 Life is reached.
Bearing life is defined as the length of time (number of revolutions) until a specific failure occurs. Predicting the life of a ball bearing is a statistical calculation of the fatigue properties of the various bearing components. "Life" is the number of hours that a percentage of similar bearings have survived under an essentially identical set of operating conditions and loads. Life can be affected by a number of factors including loads, speed, lubrication, fit, maintenance, temperature, contamination, and others. Because of the diverse variety of contributing factors, it is extremely difficult to predict life precisely. Because handling and contamination damage can dramatically reduce bearing life, bearings should be properly stored, mounted, dismounted, and inspected. Optimized performance and life is also contingent on appropriate lubrication and sufficient protection form foreign matter. Bearings should be stored in a cool, clean, low humidity environment free of dust, shocks and vibrations. Proper fitting, using specialized tools and techniques, will also help maximize bearing life. Further information is available under the section of this website.

ypically, answers to these questions might include: “The end of life comes when the bearing or bearings are no longer fit for their intended purpose,” or “When it stops rotating.” Unfortunately, these answers are neither specific nor adequate.
In bearing manufacturers’ catalogs and most engineering design books, the phenomenon that limits bearing longevity and reliability is termed rolling-element fatigue. This phenomenon has been studied for more than 120 years beginning in the 1890s with the pioneering work of Richard Stribeck in Germany, as well as the early part of the 20th century with John Goodman in Great Britain and Arvid Palmgren in Sweden.
Palmgren’s contributions probably were the most significant to rolling-element bearing technology. In 1924 he provided the foundation for rolling-bearing life calculation. He articulated that bearing life was not deterministic but rather distributive. He meant that no two bearings in a group run under the same conditions or will fail at the same time. He proposed the concept of an L10 life or a time at which 90 percent of a population of bearings will survive and where 10 percent have failed. He was perhaps the first person to propose a plausible approach to calculating the life of a machine element.
The source of most engineers’ practical knowledge of ball and roller bearings comes from bearing manufacturers’ catalogs. For about 90 to 95 percent of machine design applications, the equations and recommendations in the bearing manufacturers’ catalogs provide for safe and reliable design. Usually, the remaining 5 to 10 percent of the applications require specialized knowledge and analysis to avoid problems.
Failure Modes
The ultimate failure mode limiting bearing life is rolling-element fatigue of either a bearing race or a rolling element. Rolling-element fatigue is extremely variable but is statistically predictable depending on the steel type, steel processing, heat treatment, bearing manufacturing and type, lubricant used and operating conditions.

according to Frankenstein, If the ball bearings were not worn out on the machine that passed the electricity to his monster's body, His creation would have been the most handsome monster in history. Sadly, there were no Dangs bearings back those days and he had to work with what he had on hand.

Lets remember its not like this is a "spinning wheel" making 100's 360º rotations per minute. Rather it is just moving slightly left and right at very slow speeds. Therefore if lubrication is maintained it should hold up. With that in mind we put it back in our store after a long departure.

My two oldest Tom Conway Devpros are numbers 4 and 5 off the assembly line. I have replaced the seals twice on each. (Rebuild seals provided by Tom under warranty) It takes 8 minutes to dismantle and 15 minutes to reassemble with a full cleaning. I worked as a machinist and welder when I was younger so I recognize great machine work. After 3-1/2 years of steady use there is still no significant play in the bearing. I dare anybody to show me one of Tony's bearings half that age that is still useable. A local friendly competitor bought one of Tony's wands and it failed within three months.
I have no doubt based on current condition that my swivels will be perfectly operational in 10 years

Rob has also reviewed the 2" Hydro-Force swivel wand. I pass on comments from the forums and other users to our engineers. They find little tweaks to improve. When choosing a wand, give this consideration as well. IMO a great wand for the money.
- 14" head
- Includes two glides
- Larger diameter solution lines make sure you get all the flow you want
- Computer aided design for the vacuum plenum reduces turbulence and improves air flow (CFM)
- Soft touch valve is easy on the wrist
- Relatively light weight, at 10 pounds more than a Ti wand but less than many competing wands
- $607
I was in the interlink Seattle store Scott and was thinking about that wand but the display model seemed to be broken, the union for locking the wand head wouldnt keep the head from moving when it was tightened down. Have you guys had any reliability issues with the swivel or the locking? Does it have ball bearings in the swivel? Any lubrication or anything needed on this wand?
First time I saw it in person and I liked the feel of it, was a bit heavy but I dont mind a heavier wand.. I hate wands that are too light and you feel like you have to apply down pressure when cleaning, like the evolution.

Hey what's the names of which for those you just listed? I still consider myself fresh to this industry and I can't help but notice biased points of views instead of facts. It's frustrating man.
