Posted on Google marek konarkowskiTrustindex verifies that the original source of the review is Google. Maria is a GREAT technician and a person as well. Very knowledgeable and very helpful. Very patient too :) Thank you Maria very much !Posted on Google Technology DepartmentTrustindex verifies that the original source of the review is Google. System was great to install and gave us the precision timing for our bells needed to integrate the new time driven and time dependent sync, thanks for making such a great product.Posted on Google Dale GruberTrustindex verifies that the original source of the review is Google. I purchased 3 Netbell systems for our manufacturing plant. First, the buzzers work great and have helped our breaks start and stop much more consistently. Even more, their customer support is INCREDIBLE. Maria is the best I've ever been helped with. She first helped me get everything wired and installed myself. About a year later, she helped me on the live chat on their website and she walked me through everything so well. Everyone dreads customer support. With this company and Maria, it is actually super helpful. You don't wait forever. You don't wait for responses. You are dealing with really brilliant and personable people. I'm just super impressed.Posted on Google Bookkeeper AtchleyTrustindex verifies that the original source of the review is Google. We were in serious need of help and Maria was AMAZING! HIGH recommendation!Posted on Google eric sandlinTrustindex verifies that the original source of the review is Google. Maria was so helpful. I had a connection problem and she help me for two days until we solved the issue. Thank you Maria!!!!Posted on Google Steve MTrustindex verifies that the original source of the review is Google. Cool product, but the service is the best part! Maria is always willing and able to help, and responds very quickly (even on her day off!) Thanks Maria!Posted on Google arturo garciaTrustindex verifies that the original source of the review is Google. I will make mine short. we had issues with trying to get connected to our network. Maria one of the support techs helped me out for about 4 hours trying to get it connected to our network. after exhausting all our options we found out that with our upgraded network we needed to get IT involved to let this device talk to network. now it is just a matter of getting all the timers dialed in and putting it in operation.Posted on Google Jeremy McElroyTrustindex verifies that the original source of the review is Google. The school I work for has been using a Linortek bell system for years and we just upgraded to a new bell/PA system combo. We're still in the process of installation but so far, they have been super helpful in answering all our questions and talking us through details, and I have been very happy with the quality of the new system in my initial testing. Highly recommend!Posted on Google Melora ChangTrustindex verifies that the original source of the review is Google. Tatiana, Maria, and Liyu are fantastic to speak to. They made everything so easy and smooth. Such a great team of people to do business with (sales, it, and management). Their service is fantastic. Thank you!
