all good

I actually bought this for my wife to chase the black birds off her suet bird feeder. It worked great with the different tones that are available. Some of birds got used to the sounds, so then they didn't fly away, but it still annoyed them.

and works as advertised . Easy placement and extremely sensitive. Goes off at the very touch of your Bike.

This alarm has saved my bike from getting stolen multiple times. I have a small apartment & I have to leave my bike outside the door. One buzz from this alarm & thiefs take off running. Only thing is I wish it had ease replacement keys as the fob broke off of my keychain one time & I just bought another alarm cuz they're so cheap. Cheap. works great. is loud af. battery life lasts forever. worry free knowing my e-bike is safe.

I was looking for an easy to add alarm to my E-bike. I didn't want a "do it all" solution (eg: taillight/horn/alarm) To me I like my systems discrete, safely apart from each other to mitigate complete failure. Anyway, The alarm is simple and easy to install in a hidden location. easy to use and pretty foolproof. To be honest you could use this alarm for so many uses other than a bike, you could add a loop to it to hang on a door knob and use it as a home/hotel/motel alarm. stick it under your dashboard of your vehicle as a quick and dirty car alarm. or even stick it on the inside door of your home safe. even as an alarm for a shed. I will definitely be purchasing a few more of these and utilizing in a few of these scenarios. well worth the money.

Best use: noise deterrent behind garage door I use it on my garage door, it is very loud if you are standing inside the garage but less loud on the outside so I have three of them on the most sensitive and most loud setting, alarm can be adjusted to different levels of loudness and sensitivity and you can program multiple units to a single remote which is very handy. I would not recommend the most sensitive setting for a bike left outside overnight or a garage exposed to the elements as it will probably annoy the neighbors, but thankfully my garage door is protected from the wind and the elements. On the most sensitive setting a light tap on the door is enough to set it off so it is not possible to mess with the garage door without making noise, and that is something I really like. Combined with a sturdy door, heavy duty hasps and heavy duty padlocks it makes for a very good first line of defence. If your door/hasps/padlocks are weak thieves are going to take their chances with the alarm, but if they know it will take them time and effort to go through your first line of defence the noise alarm becomes an effective extra layer of security. I recommend installing two for more noise, three is rather excessive.Reading some comments here, this is not a car alarm and not a proper motorbike alarm either but you can use it on a motorbike as an extra layer of security to complement your padlocks, chains etc. If used on a motorbike you want to find the optimal spot so it is hidden away but at the same time can pick up vibrations easily and it is not too muffled by surrounding material. Again two will do a better job as a deterrent. I haven't had any quality issues yet, batteries last a few weeks then start beeping to let you know it's time to replace them, all in all good product for the price. Recommended for garage doors

Alarma en bicicleta impecable.

Works very well. A short buzzer noise if bike is gently nudged. Loud noise if moved away.The instructions should be improved. The 7 volume levels are almost the same.Easy one to one pairing. I might try to share remote fob with two bikes.You could also place these on inside of a shed, or locked closet/cabinet.Be aware that the remote fob does not tell you anything, it's the noise at the bike notifies you.

Delivered earlier than expected. Product is as advertised. Great purchase!

He comprado esta alarma con distintas marcas finales pero son del mismo fabricante, suena muy fuerte si estas a un lado resulta ensordecedor pero con unas 2 habitaciones de por medio ya no se escucha tanto, algo normal, la puedes pegar o amarrar, en una moto la tengo pegada encima del motor y en otra amarrada con cinchos y no he tenido problemas de fijación, el control es cómodo pero se despinta despues de unos meses, las pilas duran unos tres meses con uso diario, en fin me parece un buen producto aunque un poco caro para lo que es, seria bueno que el próximo modelo puedas cambiar el patrón de la alarma pues algunos escuchamos mejor algunas frecuencias y otras no, para percatarnos de su activación con mayor facilidad.

I just got this alarm. Some first impressions:==== INSTRUCTIONS ====A lot of reviewers have trouble with them. While they're grammatically a bit of a mess, you can get past this and all functions are addressed. Without very little trial and error, I was able to program the volume, sensitivity, and pair a second alarm to the same remote.==== ADJUSTABLE VOLUME ====This is a major reason I chose this KCMYTONER-branded version over others. 113 dB can be really loud, indoors especially. The three selectable levels are a good option and 'spaced' reasonably for choosing volume.HOWEVER, whichever volume you choose seems to affect all sounds, not just when the alarm is triggered. 'System sounds' when arming, disarming, and programming are at the same volume. Even the lowest volume level -- which is fairly tame for the alarm side of things -- is pretty loud for just pressing some keys on the remote. I've posted a question to see if there is anyway around this. If you're using this indoors, or If you want arming/disarming to be discrete, this is a concern. I don't want to be exposed to 113 dB every time I press a remote key.==== PAIRING ADDITIONAL REMOTES ====The programming steps are easy to either control one alarm from multiple remotes, or control multiple alarms from one remote. With the one remote / two alarms setup, it was easy to re-pair; once paired, you program two alarms at the same time and identically, which I liked. Downside: if you wanted to program the two (or more) alarms differently, you'd have to either move one out of range, or remove it's battery.....==== REMOVING THE BATTERY ====A big pain. There is no sliding battery cover, and it's not as simple as removing a screw, although there is one (and a screwdriver was included). After you remove the screw, you have to pry the housing of the alarm open, basically the way a repair technician might do when repairing a phone. Never done that kind of thing and don't have specialized plastic tools to do it? You're probably going to break something. Even if you don't, the stress this puts on the many little plastic clips that keep the housing snapped close is not good; over time they will break off. I wouldn't expect this thing to survive multiple battery changes, unless you're extremely, extremely careful. This makes it seem a bit disposable, which I'm not a fan of with any electronics, even when it's affordably priced.==== VIBRATION SENSING ====The jury is still out on this one and I'll update this review later. It is nice that the alarm has 2 levels of reacting: a short warning tone for the first 'hit,' and then a full alarm if a second hit comes within a few seconds.But, it seems that it takes more of a hit to trigger the warning, then to trigger the full alarm. Even with the highest sensitivity while testing, I had to disturb the alarm a couple of times in some cases before it 'warned,' and then barely touch it to trigger the full alarm.There also seems to be a built in delay of a few seconds between arming the alarm and having it react to the first movement (this could be by design).==== CONCLUSION ====Not a bad product, especially for the price, but I'll have to spend more time around it to decide if any of its shortcomings are deal breakers.

super easy install was skeptical of the product because of price . so happy with my decision to purchase this alarmsuper loud nice remote just bump my bike first it warns then if bumped again wow take that thieves hehehaha leave my bike alone . where I live bike theft is terrible as it is a bike town I have a ebike couldn't afford to buy another this gives a comfort level I can handle as I go in a store no free access to mess with my transportation while I do my business or enjoy a meal and a beer in peace not paranoia instead . if you want a little security guard to watch your bike when you cant then buy this awesome little alarm could not be more pleased !!!!
