In this regard, it is not recommended to use FORWARD Valencia 1.0 on dirt roads. The main advantage of the bike is its price.

Main advantages:

The presence of a trunk and fenders
Low price
Reliable frame
small mass

Minuses:

No disc or rim brakes
Lack of a speed switch
No depreciation

Merida Juliet 40-V (2014)

Bicycles for girls must have a low frame. And that’s exactly what the Merida Juliet 40-V got. At the same time, this vehicle is not inferior in its qualities to other mountain bikes. In particular, it weighs only 13 kg — it is felt even during the trip. Also, the unit received at its disposal a spring-elastomer fork with a 100 mm stroke. 26-inch wheels are designed primarily for traveling on asphalt, but they also do not shy away from the primer. The stop is made by means of rim brakes.

Main advantages:

Not the highest price
The presence of a suspension fork
small mass
Comfortable saddle

Minuses:

The simplest speed switches
V-brakes

STELS Miss 6000 V 26 (2015)

This bike is made in Russia. It has a low frame and a comfortable saddle. First of all, this model was created for trips around the city. But practice shows that the unit feels good on country roads. The 26-inch wheels are equipped with a double rim made of aluminum alloy. They are able to overcome almost any obstacles. A spring-elastomeric fork provides a comfortable ride on the primer. Unfortunately, it is impossible to block its course, but not a single bike from this price segment has this function. The desire to save money did not allow the creators to place disc brakes on the wheels. Instead, standard rim «vi-breaks» are used for deceleration. 18 speeds allow you to easily climb the hill and move down the slope. Shimano products are used here as attachments.

Main advantages:

low price
Wings included
small mass
Attractive appearance
The presence of a suspension fork

Minuses:

Revolving handle levers

A basket is attached to the handlebar, allowing you to carry small items in it. The child should definitely like the bright appearance of the bike. Not only the frame is painted here, but also the fenders, the trunk and even the saddle. First of all, the vehicle is intended for girls.

This model is intended for children whose age is equal to or greater than 4 years. A bell is placed on the steering wheel, which teaches the child to warn random passers-by about himself. Removable support wheels help you ride without trying to keep your balance. Attachment equipment is missing. In this regard, the bike has only one speed and a foot brake. The vehicle comes with fenders that protect the child from mud and splashes. The buyer will not receive only a trunk that could help the child transport small items.

This helps to correctly distribute their forces to overcome descents, flat areas and ascents. The bike also received Power disc brakes, which help to stop almost instantly. The SR Suntour XCT-26 suspension fork is made using spring-elastomer technology. Its stroke is 80 mm. This saves the cyclist’s hands when overcoming potholes in the asphalt and other irregularities.

Merida Matts 40-MD (2014)

The creators of this bike have tried to use quality materials and good attachments. In this regard, the buyer gets the opportunity to drive not only around the city, but on dirt roads. Shimano’s 27-speed system helps you balance your power uphill and downhill. Even as part of the vehicle there are disc (mechanical) brakes. They allow you to stop almost instantly, even if the cyclist is currently moving down a steep descent. The suspension fork, which has 100 mm travel, also looks good here. A special switch allows you to adjust the spring rate or completely block the stroke. The latter action is useful during a city trip on smooth asphalt, when you need to put all your effort into pedaling. 26-inch wheels have a double rim. Perhaps the Merida Matts 40-MD is the best value for money if you want to buy a bike specifically for country trips.

Main advantages:

Attractive appearance
Good suspension fork
Disc brakes
small mass
Lots of speeds

Minuses:

A resolution of 1024×600 pixels contributes to displaying a clear image — pixelation is difficult to see, even when the device is very close to the eyes. The 16:9 aspect ratio makes it possible to recommend the device only to fans of large-format photographs. Recall that most often pictures are saved with an aspect ratio of 4:3, they will be displayed on such a screen with black stripes on the sides.

Rekam DejaView HD-R8

The Rekam DejaView HD-R8 digital photo frame should be used with care. It may not recognize a memory card with a large capacity. It is recommended to connect no more than 16-gigabyte cards to it. This is usually enough for a huge number of photos or a few decent-sized videos. The Rekam DejaView HD-R8 comes with a remote control. But it also has one drawback — keystrokes are not always determined by the system. The rest of the digital photo frame should only please. Its 8-inch screen has the usual resolution of 800×600 pixels. The 4:3 aspect ratio should be fine for most photos. Power is supplied from the network, there is no built-in battery. Because of this, when the power is turned off, the time and date may be lost.

The best mobile satellite dish

Azure AS-35T

An ordinary satellite dish is attached to a wall or roof almost tightly. You can remove it only with the help of special equipment, and there is no guarantee that it will work after that in a new place, which cannot be said about a mobile satellite dish. Azure AS-35T is easy to attach, and if you are moving, it is very easy to remove and store in a plastic suitcase. You can even install an antenna on the roof of a car — remember the shots from foreign films? After that, it remains only to get hold of a means of decoding the signal. Now even a laptop can act as it, to which a USB-card capable of working with DVB-S and DVB-S2 standards is connected.

Main advantages:

Possibility of easy transportation
Easy installation
Rich equipment

Minuses:

Supral 0.9 m

This offset satellite dish is perfect for receiving signals from almost any satellite. Used to work with Rainbow TV, Telecard, Sirius and Hotbird. 90 cm diameter allows you to use the plate in all corners of our country. The wall bracket is able to withstand very serious loads — the antenna will not move even by 1 mm. Interference in signal reception can only occur when the wind speed is above 25 m/s, which, you see, happens infrequently. There are no large logos on the surface of the plate — this is also a plus: not everyone wants his gadgets to serve as a free advertising platform. We understand and approve.

Main advantages:

Large antenna diameter
Decent gain
Good stability even in strong winds
Low price

Minuses:

LANS-65

The cost of a LANS-65 satellite dish may seem overpriced. What can you do, this is one of the best cymbals with a 65 cm diameter: it was created using offset technology, it is close to an ideal parabola (in this parameter it greatly surpasses its all-metal competitors). There is a self-cleaning function, so the antenna catches the signal qualitatively even in heavy rain or heavy snow. The dish can withstand any wind, with the exception of a serious hurricane — only in this case interference may occur. The steel base is powder coated. This plate can be used for several purposes. Firstly, with its help, a signal from a satellite is caught (NTV-plus is also supported). Secondly, the antenna works well with amateur radio bands. Not bad, right?

Self-cleaning function

SKYMAX 1.2 m

This large antenna is made using offset technology. It is often purchased by residents of the Southern Federal District and the Urals, from which many satellites are very far away. The large diameter accumulates the signal, sending it to the reflector with increased strength. The device can be mounted on a wall or roof at almost any angle, however, the bracket will have to be selected individually. The antenna is stable, made of steel 0.8 mm thick. The manufacturer claims that something bad can happen to SKYMAX only when the wind strength is over 60 m/s, which is still rare for Russian regions. The polyester coating protects the steel from moisture and high temperatures. Perhaps this is one of the most reliable satellite dishes, frightening only with its size and the absence of a bracket in the kit. But you’re not shy, are you?

Can be installed at any angle
Sustainability
High-quality signal reception

SKYMAX 0.55 m

The SKYMAX 0.55 m satellite dish was created using offset technology. The low price tag is explained by the small diameter of the plate. The device should be bought by residents of large cities located as close as possible to the satellites. Only in this case, stable signal reception is guaranteed. The minimum dimensions can also be considered an advantage, as they provide excellent stability. Only hurricane winds can damage the antenna. The plate is made of steel with a thickness of 0.5 mm, so it is easy to mount it. A polyester coating protects the surface from rain and sunlight.

CORAB ASC-800PR/C

In fact, this is still the same offset plate made of steel. The thickness of the metal is 0.6 mm, which makes the device very light. Sufficiently large dimensions allow the antenna to be used to receive a signal from distant satellites. It also increases the gain. Steel in the creation of CORAB ASC-800PR / C is used not simple, but galvanized — goodbye corrosion! The surface of the plate is coated with polyester paint. It eliminates the slightest irregularities that affect the quality of signal reception.
