The Lightning Bee is one of our less popular models, although those that have experience with it find it to be trustworthy and dependable. Hardwired for intelligence, wit, and eloquence, this somewhat bulky machine interfaces well with most other models. Aspects of this model that we receive praise for are its loyalty and listening/reacting reception nodes. Problems have been reported regarding its ability to establish connection with numerous machines at once, therefore you should keep it interfaced with one machine at a time if at all possible. This model is considered flawed due to its overactive electrical manipulator which can lead to serious injury or death. To counteract this,we installed a failsafe chip,which automatically shuts down the entire interface for an extended amount of time. Apart from these unfortunate design downfalls, this model is well-built and versed in numerous topics. It is not for everyone, but those who use it to its full potential are almost always satisfied. Thank you for researching the Lightning Bee model, and we hope we have been helpful in your quest to find a machine that fits your needs. More information or upgrades for your current unit can be found on-site in stores or on the internet. Have a wonderful day!
