Comparison Philips Series 7000 MG7940/15 vs Philips Series 7000 MG7720

— Blade for cutting. The device is equipped with a classic hair clipper. Hair clippers usually have a fairly wide blade, allowing you to capture a large amount of hair at one time. In beard trimmers, the blade width is slightly smaller, but still allows you to fully care for a certain area of the face.

— Additional blade for cutting. An extra blade can serve as either a backup or a supplementary tool. While spare blades usually match the width of the main blade, auxiliary ones are typically narrower. A narrower optional blade is primarily used for precise detailing and cutting intricate designs. Conversely, a spare blade can come in handy when the main blade is entirely dull.

— Trimmer for goatee. The goatee trimmer is a special nozzle with a narrow blade, with which it is convenient to shape the contours of the goatee and easily care for this type of beard. A characteristic feature of this nozzle is a blade about 20 mm wide. The goatee trimmer can be represented as a replaceable nozzle or an additional blade built into the clipper.

— Trimmer for ears and nose. The clipper is equipped with a special nozzle that allows you to effectively and safely cut hair in the nose and ears. The ear and nose trimmer is usually a small cylindrical blade, the diameter of the cutting head is usually 5-7mm, and the length can be up to 30-40mm. The pres...ence of a trimmer for ears and nose allows the machine to take a more comprehensive approach to hygiene and hair care.

— Eyebrow trimmer. Eyebrow trimmer — a special attachment in the form of an oblong cutting head that allows you to care for eyebrows, correct their shape, and also shorten thick and unruly hairline. The eyebrow attachment is often double-sided. On the one hand, the trimmer can be equipped with a 3-4 mm high comb, which allows you to protect the eyebrows from excessively short cutting, and the other side is usually represented by a bare blade, which makes it possible to cut off excess hairs on the eyebrow line under the root.

— Foil razor. The foil razor head is tailored for trimming short stubble. The mesh effectively and delicately cuts through three-day growth, leaving behind a smooth complexion without discomfort. Numerous clippers featuring foil razors enable shaving without the need for foam, commonly referred to as a "dry shave".

— Body trimmer. The body trimmer is an accessory designed for removing hair from the torso and sensitive areas. The shaving head for body grooming usually features a dual structure. The primary component is a conventional blade that effectively handles coarse hair. Positioned behind the blade is a shaving foil that ensures a clean shave for any remaining stubble. Additionally, the body trimmer often includes a detachable 3 mm comb. When dealing with dense hair growth on the initial pass, using the fixed comb is recommended as the foil shaver might not be as effective.

— Universal comb. The adjustable-height comb provides seamless hair cutting transitions without the need to change attachments. Altering the comb's height is easily achieved on-the-fly by pressing the latch and shifting the comb. These combs offer convenience as they enable cutting with a single attachment, maintaining workspace organization. However, due to their intricate design, the reliability of such attachments may be compromised. The adjustable comb attachment is versatile, with typical models allowing you to select any height between 1 to 20 mm.

— Comb for cutting behind the ears. Comb attachment for precise work behind the ears. Allows you to perform a smooth edging along the lower border of the scalp in the area behind the ears.

Clippers and trimmers are often equipped with fixed-height removable combs. The more combs in the kit, the smoother transitions the device can make. The standard set usually includes 3-5 combs, more advanced models may have 7-10 combs of a fixed height in a set.

The number of haircut length options provided in the design of the clipper or the design of the nozzle. The more such options, the more versatile the clipper and the more cutting options it provides.

The width of the operating tool (blade) of the clipper. A wide blade is important for head hair trimmers, as it allows you to capture more hair in one pass and cuts faster. In turn, beard and mustache clippers use narrower knives, which is useful for fine work to give facial hair the desired shape.

The performance of the tool, the maximum rotation speed of the motor and how well the device handles with thick and coarse hair depends on the power of the electric motor. So, for cutting thick head hair, you need a clipper with a power of at least 15 W, the performance of such a device is usually enough to ensure a motor rotation speed of 10,000 rpm. But there are also more powerful clippers(from 20 W). Trimmers for beards and mustaches usually need 5 W of power. Such models most often have a performance of 3,000 – 5,000 rpm.

— Self- sharpening blades. Blades made using a special technology, thanks to which they sharpen themselves, due to friction against each other in the process. Thus, the blades remain sharp at all times, and their maintenance is limited to the replacement of worn blades.

— Function of thinning. Thinning in hairdressing is called cutting the ends of the hair at different levels — as a result, after the haircut, the hairstyle looks more natural and magnificent. In machines, special thinning nozzles are usually used for this.

— Wet cleaning. The clipper's capacity for wet cleaning of its attachments, allowing them to be rinsed under flowing water, is a notable feature. It's important to clarify that this pertains exclusively to the attachments – not all models with wet cleaning have waterproof casings (see below). Nevertheless, even without a waterproof casing, it might still be feasible to clean the attachments without detaching them from the device. In general, wet cleaning is frequently more efficient, quicker, and precise compared to dry cleaning.

— Waterproof body.In this context, a sealed enclosure is indicated, enabling the machine to withstand water exposure without adverse effects. The extent of protection can vary; certain models tolerate brief water immersion, while others can operate even when submerged. These specifics should be detai...led in the accompanying instructions. Nevertheless, for clippers used in environments with elevated humidity (like bathrooms or wet areas), having such a water-resistant enclosure is greatly preferred, and sometimes obligatory.

— Built-in vacuum cleaner. The clipper is equipped with a vacuum cleaner, which greatly facilitates cleaning after cutting. The suction hole located under the blades sucks most of the cut hair into a separate reservoir. Of course, there will not be a 100% return, but there will be much less hair scattered on the floor. However, when cutting a beard, a vacuum cleaner will do just fine.

— Laser pointer. The presence in the electric razor of a laser in the form of a straight line. With its help, you can easily, and most importantly, evenly and symmetrically trim the desired areas.

The ability to charge the battery of the clipper from the USB port of the computer. This function is not particularly significant when using the machine at home, but for travel it can be useful: if necessary, the battery can be recharged from the USB port of a portable computer (laptop or tablet). In this case, the connector in the device itself can be microUSB, USB-C or branded, which will require an appropriate cable.

The clipper offers the capability to adjust its operating voltage, typically ranging between 110 and 230 V. Given the varying electrical network voltages across different regions (e.g., 230 V in Europe, 110 V in North America), this feature proves advantageous when using the clipper abroad. Some devices possess an automated voltage adjustment feature, requiring no user intervention, while others necessitate manual adjustment. It's important to emphasize this aspect before commencing clipper operation, and in cases of manual adjustment, it's crucial to verify the correct setting on the switch.

— Metal. High-end clippers/trimmers use a metal body. Typically found in professional models, and occasionally in semi-professional ones, a metal casing ensures remarkable durability and resistance to heavy use. However, this design substantially elevates the device's weight and cost.

— Plastic. Mostly low-cost clippers/trimmers are equipped with a plastic case. The plastic case is lightweight and easy to care for. Among the shortcomings of plastic, only low strength can be noted. If you intensively use a trimmer/clipper with a plastic case, then the working surface of the device will quickly become covered with scratches and scuffs.

— Metal/plastic. Semi-professional clippers/trimmers commonly feature a combination of metal and plastic casing. These models incorporate metal with plastic inserts. This approach maintains a high level of reliability while using plastic inserts to lower device costs and enhance user-friendliness. Clippers with combined casings are versatile for both home and salon use.
