(THIS IS A TRUE STORY AND 1 OF THE WORST EXSPERIENCES I'VE EVR ENCOUNTERED)keep up the good work Amazon.I would reccomend dropping the nettalk device. ### ⭐ Rediculous *by K***L on Reviewed in the United States on October 26, 2013* I purchased this unit and after around 6 months use (the unit stayed in one place, was not moved by anything) my calls started to cut out. This was very obviously a physical short of some kind, because if you touched the unit it would reboot.The problem eventually got bad enough that I had to return it. I contacted tech support numerous times, and the phone tech support is worthless (after an hour of holding, I gave up). After much arguing with nettalk support, they very reluctantly issued an RMA (10 months after purchase).I sent my unit in using the RMA prepaid shipping label printed from their website. I NEVER GOT ANYTHING BACK. It's been over a year now, so I definitely waited long enough. I wouldn't recommend this company to my worst enemy. They treated me like total crap, and in the end basically stole my unit. The very least I expect would be for them to return my defective unit so that I could attempt to repair it myself. Maybe they could have even contacted me.Good riddance I say, I'll never do business with this crooked company again. ### ⭐⭐⭐⭐⭐ Great Phone Line Alternative *by I***E on Reviewed in the United States on November 1, 2011* The Nettalk Duo Voip by Dell is a great alternative to a land-line telephone. You must have high speed DSL or cable internet in order to use this product. I did not own a land-line and did not use nearly all my cell phone minutes. I found this to be an efficient way to save money.I get a clear signal while talking on the phone. In order to make an outgoing call, you will need to dial the 3-digit area code before the main phone number. I can handle dialing 3-digits if it means I am going to save hundreds of dollars a year. There is no long distance charge for calling anywhere in the United States or Canada.The Nettalk Duo can plug into your computer, modem or wireless router. This way you can still make and receive calls even when your computer is turned off, unlike many of its competitors. After hooking the Duo up, I had to reset my telephone in order for it to register. It has worked great ever since.I highly recommend this product as a cost-saving alternative phone source. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/17170732-duo-duo-01](https://www.desertcart.pl/products/17170732-duo-duo-01) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-02*
