Deerma Filters Electric Vacuum Compatible with Deerma
at 2023-03-20For those who have read the vacuum cleaner review that I wrote and are waiting for the filter review.
Origin/Authenticity.
No comment.Application to the bin.
If the filter is not applied correctly to the bin even once, the vacuum cleaner will be thrown away in 10 minutes instead of 10 years. The included filter that comes with the vacuum cleaner fits correctly and "locks" in place without needing to be touched by a person, under its own weight. If you need to apply more force than necessary to bend a coffee straw, then the filter is definitely being placed incorrectly. During the application check, this filter required more force as it did not fit differently. Perhaps over time, it will take the shape of the bin correctly and fit more easily. It should be noted that there were no measurable differences in the filter for application to the bin. Like the original, this filter also has a manufacturing flaw (see circle in the photo) in the frame that fits into the bin. Use a knife to carefully remove it.Build quality.
Compared to the original filter, it was found that:
A) it is two grams lighter.
B) it is 3 millimeters shorter.
C) it is 0.2 millimeters thinner.Pollutant retention.
This filter has much greater airflow than the used filter I have. This is attributed 90% to the pollutants that remain in the old filter, while 10% is attributed to the thinner filter used to make the replacement. Greater airflow equals more pollutants entering the engine and gradually destroying it.Final conclusion.
Replace your filter only if it is damaged, or if after any cleaning, the suction power and air expulsion are extremely low. In this case, carefully place the new filter in the correct position and see if there is a difference. If there are no differences, then perhaps the vacuum cleaner needs servicing or replacement. The product receives 5 stars as there is no alternative solution or other product for comparison. Purchase price is 3.39€- Is it as it appears in the photo?

Impresses with its range, reliability, quality, size, weight, and cost. I have applied it in telecommunications, computers and peripherals, air conditioning, audio and video systems, consoles, household kitchen appliances, bathroom, living room, as well as security systems and home automation both inside and outside the house. The applications for vehicles are endless. I wish they sold them by weight and not by piece. Purchase price 4.56€

Electra EH-0520IC Induction Countertop Single Burner Black
at 2023-01-20Update 7/11/23:
When purchased 10 months ago, it was the only product in its category with an extremely low price of €19.90 and due to its capabilities, it was literally unmatched - a unique solution (read the original review below). Currently, there is a competing product priced at €17.27 which also has a timer!.. It is the best seller on the company's Esperanza model EKH011 on Skroutz, but it cannot easily be converted into an ultra smart device. So, this remains a unique cheap DIY ultra smart solution.Original review 20/1/23:
Do not buy this product if you are not an electrician, electronics expert, or hacker. By paying an extra 5 to 10 €, you can buy another product with a timer. This device is ideal for the aforementioned category of people, not to become "smart," but "ultra smart." The fan makes noise and works very well for a long period of time after the operation is terminated. If you want, you can extend the fan's operating time by adding supercapacitors - extremely useful if the vessel is not immediately removed from the stove after the operation ends. If the noise bothers you, use a low noise - high airflow fan. The fan is powered by 18 volts, but this is a problem that you know how to solve. If you choose not to replace the fan, add the opening and closing of the lighting in the rooms you desire to the operation to be notified of the end of the routine. For the upgrade, you will need 2 Sonoff dry contact modules. €6 each. For the power source, use the power supply that you kept with the broken USB port, which was not worth repairing. Be careful with the terminals of the power cable that goes into the board. It is recommended to replace the terminal in order to incorporate a cable that goes to the power supply, which must have strong insulation or be at a safe distance from the induction plate during operation. In general, for easy repair/maintenance, it is recommended to install terminals/plugs wherever you desire. To immobilize the 5v power supply, use hot glue before and after the board on its cables, but not on the board itself. The modules can be joined with a little hot glue between each one's relay, just reverse and turn one of the two upside down. The above creates a single box without short circuits and easy access to the pairing button. This box can be fixed with a piece of plexiglass and 3mm screws, as shown in the photo. It is recommended to replace the thermal paste on the temperature sensor. Finally, in the scenes of eWeLink, create the following after you have 1) selected names for the 2 modules: power and function respectively. 2) selected the inching 0.5sec function for both modules.1) Tap to perform. 1) Activation type can be different.
2) Power on (starts at 1300 hot pot, actual wattage 1,160).
3) Delay 3sec (necessary for proper operation).
4) Function on (goes to 2000 stir fry, actual wattage 1,430).
?) Optional: delay 3sec + range hood opening.
5) Delay - 5 to 10 minutes (until the water boils).
6a) Function on (goes to 1600 soup, actual wattage 1,420).
6b) Delay 3sec (necessary for proper operation).
7a) Function on (goes to 1600 steam, actual wattage 1,400).
7b) Delay 3sec (necessary for proper operation).
8a) Function on (goes to 1,000 boiling, actual wattage 1,030).
8b) Delay 3sec (necessary for proper operation).
9) Function on (goes to 80 milk, around 3 seconds on and 6 seconds off at 860 watts for 3 seconds).
10) Delay (for as long as the food needs to be prepared).
11) Power on (device shuts down, fan continues).
Optional additional functions:
12) Delay 3sec (necessary for proper operation).
13) Range hood closing and/or opening - lighting-music or other device control in desired rooms, with or without repetition (additional equipment required).Induction coil dimensions:
Outer diameter 15.5cm (usable)
