Très pratique. Les appels automatisés sont presque tous automatiquement bloqués. Pour les autres qui se font très rares, il suffit d'appuyer sur le bouton rouge BLOCK et le tour est joué. Un gadget essentiel quand on se fait harceler au téléphone. Instructions faciles à suivre.

Funktioniert tadellos. Leicht zu handhaben. Etwas gross im Durchmesser.

Est très efficace, je ne reçois quasiment plus d'appels indésirables (trois en 10 jours au leu d'une quarantaine) mais je n'ai pas pour l'instant testé toutes les fonctionnalités

Me pareció Exelente para todas esas llamadas de EXTORCIONADOR tu solo dejas los teléfonos que te interesan que te llamen

The manual came with a coffee ring stain and the page with the optional feature codes seemed to be stained with dried food or coffee. The device has no serial number (apparently registration just collects your contact information which is also a bit sus) and the optional features of blocking foreign calls, unknown calls, private calls and/or VOIP calls are of marginal benefit especially as more people abandon actual land lines for inexpensive VOIP lines. The blocking foreign, unknown, private, and/or VOIP would be useful if you could have an allow list specifically for the numbers blocked by these options but it seems as if the allow list is for when the device is set to block all numbers except for those in the allow list. There does not seem to be a way to update the preloaded database of 10,000 common spam/scam numbers so it's probably already way out of date. With the spammers and scammers often randomly generating their caller id's, such a device is probably of marginal use but it's better than nothing and allows you to block more numbers than your cordless phone and phone service normally allows and will block the first ring or two while it sorts out whether or not to block (phone providers in Canada are already required by law to block the most common known spam/scam numbers but the VOIP providers will always let the first ring through. The device does not have a power jack, it apparently uses line power from the phone lines themselves. The default "block mode" is basically blacklist security where all calls except thoseexplicitly blocked are allowed whereas the optional "allow mode" is the whitelist security where all calls are blocked except where explicitly allowed. There is no way to enter patterns such as area codes and or prefix and there's no way to block toll numbers from calling in. There's simply a lot more that could've been done despite how futile using the voluntary sender provided caller id for security. I think it will help a little but only just a little with the most benefit being to block the first ring from the VOIP provider while they sort out the number through their spam/scam database which we already know doesn't stop all the spam/scam calls and of course being able to enter 2,000 more numbers to block in our feeble attempts to do something however useless about the frustratingly common spam/scam calls. I guess, the alternative is to pay your phone provider for the premium subscription with their more updated unwanted caller databases rather than just the federally mandated minimal protection they are required to give you (Canada requires that at least something be done to prevent unwanted calls to all customers but there's really no standard as to what's sufficient but I have seen a few calls blocked by the VOIP provider as the phone rings once and displays "Checking" before hanging up).The blocking device also has two other jacks labeled "Line 1" and "Phone 1" as opposed to the "Line" and "Phone" jacks that you use, the manual does not say what they are for but one guess would be to support a second line.Oh, and it looks like a real cheap piece of plastic.

Overall, I certainly recommend this unit as an effective means to block robocalls and scam calls. The unit was very easy to set up. You can set it up either in series with one of your landline phones or in parallel mode. The only difference I can determine is that, in parallel mode, the phone to which it is connected also rings one time before the unit either blocks the call or lets it through. With that in mind, I'd suggest setting it up in series with your bedroom phone, so you won't hear the first ring.You have to work with it for the first week or so because there will be a lot of robocalls in your local area that aren't in the unit's memory. We've been working at it and now, after two weeks, we get maybe 1-2 calls per day that aren't yet blocked. Go ahead and set up the options, such as blocking all VOIP and private calls. It's easy to follow the instructions about how to do this. It may take 2-3 times to finally block a call you think you've blocked already.The only problem we're having is that, every so often, the unit will not release the call. Our phone's display reads "line in use". I have to disconnect the unit before I can get a dial tone. I'm not sure if this has to do with series versus parallel or perhaps because our alarm company is interrogating our system. I plan to follow up on both of these issues.
