I put it on a new CB125F in July 2021. I don't use the bike much. In September 2021, I didn't use it for 7 days, I went to disarm the alarm, the alarm disarmed but did not make any visual or audible signal as it should, because it drained the battery. Luckily, the bike had enough battery to start, so the battery was recharged afterwards.

In November 2021, I didn't use it for 20 days. The alarm doesn't work, the instruments don't turn on, the starter doesn't work, due to a dead battery, the voltmeter of the remote control showed 2 volts! I go to the workshop, leave it for charging. The mechanic tells me that the battery has been destroyed and that it will kneel again in a week if I charge it, so I put a new one with 35 euros GS. I put it in. And with the new battery, the same things happen. I have to ride it every three days to prevent the new battery from getting destroyed. It's a real Chinese product.

To understand, in the manual it says maximum consumption <3.5mha, when for example Elser says 0.6mha in economy mode, which is about six times less.

I had the same alarm before on a Suzuki address 125, but I used it daily and had no problems.

Conclusion: if you don't ride daily, don't install it.

Note: Discharges occur with the alarm disarmed (!!!) after I put the bike in the garage at night.

Neither cold nor hot. I used it for a month on a scooter and then took it out. The remote notification is good, as well as the range, but it caused me anxiety. I had to constantly have the remote nearby and keep checking it to ensure it had range. I would like it to have a display showing the alarm history and also an indication that it lost connection with the motorcycle. The signal bars indicator is not very helpful, as the signal can be affected by various factors, such as a passing truck. Also, the buttons on the remote are not convenient at all. They are on the sides, small, and can easily be pressed accidentally. Many times, without realizing it, I would accidentally press a button and the alarm would go off silently (without sound, only lights and notification on the remote). It requires careful study because the user manual is somewhat confusing. It also has a battery voltage indicator, but only when the alarm is activated and for two seconds. The automatic rearming every 30 seconds is a big negative. You disarm it and until you get organized (helmets, gloves, lock, things on the seat), it arms again. This feature should be able to be permanently disabled somehow. It also has a backup 9-volt battery. I don't see this as a positive. This battery will definitely fail at some point (cheap Chinese), it will oxidize, and it will leak fluids. There is no indication of a low backup battery, no notification of a problem, nothing. The backup battery is not meant for much. Also, the motorcycle battery should not be removed or disconnected for long periods of time because then the alarm consumes the backup battery. The activated alarm consumes about 4mA, while deactivated it consumes about 1mA. The remote control had not consumed any battery power in a month. The second remote control is simpler to use. Anyone who has the time and willingness to have "contact" with their motorcycle should consider adding it to their list of options.

I bought it for 95 euros, it is a good Chinese product which I believe has maybe saved me from theft at least once in the center of Athens where Beverly scooters are at the top of the theft list. 5 stars because I easily connected it to the battery and it does its job. The main thing is that it has the option, apart from sounding an alarm and notifying you on the remote, to also have it silent and only hit the remote so as not to disturb the neighborhood with noise and to have control. What has proven to be more useful in my case, living on the 4th floor and the scooter not being below but on another adjacent street, is that the siren cannot be heard, but the remote beeps if something happens and notifies through walls up to a distance of 50 meters. The battery in the scooter has not died in the 1 year that I have been using it. The remote is charged every 2 weeks via USB. As a downside, I would mention the volume of the siren, which I would like to be stronger for a more powerful danger signal, although it is not exactly low. Along with the alarm system, I also put a chain on the front wheel, with these measures I am optimistic

Value for money alarm with remote notification from a reliable Chinese manufacturer with years of experience.

It does not trigger with the slightest movement, noise, etc. But someone cannot remove the motorcycle cover without triggering it with the sensitivity set to the highest level 8 (adjustable from 1 to 8).

Small size of the unit and siren, so it was ideal for me (naked with minimal free space under the seat). Loud siren with warning. Perfect signal even with covers, etc. on the 3rd floor. With the bike parked on the road in the Athens Tower, I was on the 16th floor and still had a signal! It has a normal signal up to 60-70 meters with few obstacles. Don't expect it to have a signal for a kilometer.

The remote with full charge (requires a USB wall adapter, the product photo is an older version) lasts me more than 35 days and has a low battery notification. I have no issues with increased battery consumption. In winter with moderate battery condition and 10-day inactivity, it still worked immediately.

One star is deducted because I believe it should cost less than 100 euros for what it offers and for the annoying automatic arming (if you don't put the key on top when disarming).

In conclusion, it is considered a good purchase, and I hope it withstands the test of time.

The 2018 xmax 300 scooter works perfectly both in terms of shock absorption and incline. The shock absorption has 8 levels of sensitivity. It has a range and arm/disarm capability of around 200-250 meters without obstacles, with walls around 100 meters. The best part is that one day, even though the controller didn't show any range, it still alerted me to a vibration that occurred about 100 meters away with a wall in between. If you want, you can adjust the alarm to disarm itself as soon as the engine turns off. If not, you can do it manually. If you arm it and then disarm it without putting the scooter in gear, the alarm will arm itself again automatically. If you generally don't arm it and turn off the engine, you will be notified audibly and on the controller simultaneously. The controller has a rechargeable battery with an indicator that recharges via USB. It flashes and vibrates when the alarm is triggered and shows the battery voltage of the scooter with a 0.3 difference from the indication on the scooter's screen. The siren is quite loud. Before I bought the scooter, it was recommended to me as a gift by three authorized Yamaha stores, one of which was MotoDiktyo, which is backed by Yamaha (this may be a benefit for them), but I don't think Yamaha would provide an unreliable alarm. It cost me 120 euros with installation. I couldn't describe it in more detail... Useless it should be
