One disadvantage to using N-TIRE is that the electricity delivered from the electrodes can stimulate muscle cells to contract, which could have lethal consequences depending on the situation.

One disadvantage of AC, the fact that the arc must be re-ignited after every zero crossing, has been addressed with the invention of special power units that produce a square wave pattern instead of the normal sine wave, making rapid zero crossings possible and minimizing the effects of the problem.

One disadvantage of minimal deterrence is that it requires an accurate understanding of the level of damage an adversary finds unacceptable, especially if that understanding changes over time so that a previously credible deterrent is no longer credible.

One disadvantage of this feature is that the computers which are actually performing the calculations might not be entirely trustworthy.

One important disadvantage of PMMA lenses is that no oxygen is transmitted through the lens to the conjunctiva and cornea, which can cause a number of adverse clinical effects.

One disadvantage of stainless steel is that, being made of thin metal, they tend to be noisier than most other sink materials, although better sinks apply a heavy coating of vibration-damping material to the underside of the sink.

One issue that can be considered an advantage or a disadvantage depending upon an individual's viewpoint, is that removing hair has the effect of removing information about the individual's hair growth patterns due to genetic predisposition, illness, androgen levels ( such as from pubertal hormonal imbalances or drug side effects ), and / or gender status.

In general, a system that contains 2 ^ N processors with each processor directly connected to N other processors, the diameter of the system is N. One disadvantage of a hypercube system is that it must be configured in powers of two, so a machine must be built that could potentially have many more processors than is really needed for the application.

One disadvantage of plastic frames is that they are more likely to tip over than a steel frame if a heavier child is riding.

One possible disadvantage the Nikon F had, compared to other professional cameras, was the fact the entire bottom and rear plate was made in one piece and had to be removed to reload the camera.

One disadvantage is that if dislocated by slipping out of the screw, the resultant sudden extension of the spring may cause the bit to scratch or otherwise damage the workpiece.

One disadvantage is that the urine antigen test only detects anti-bodies towards Legionella pneumophila ; only a culture will detect infection by the other Legionella species.

One of the pioneers in the construction of metal aircraft, the Breguet 14 day bomber, perhaps the most famous French warplane of all time, was made almost entirely of aluminium.

One of the approaches is using an aerosol of burning red phosphorus particles and aluminium coated glass fibers ; the infrared emissions of such smoke curtains hides the weaker emissions of colder objects behind it, but the effect is only short-lived.

One such, aluminium oxynitride, is much lighter but at US $ 10 –$ 15 per square inch is much more costly.
