The product we are currently selling is an accounting and communication module for condo hotels and fractional properties.

Tech support had me remove the battery for the third time in 32 days.

In batteries that energy is stored in some form of chemical reaction, that then reverses to release the energy.

Your time is too valuable looking for the next deal or improving systems to be changing batteries in a smoke alarm or unclogging a disposal.

Maintenance to some degree is allowable as well, be reasonable, a tenant can't be expected to tow a car to have the battery charged!

Also, grid-independent systems are a lot more expensive because you need to add battery storage.

However, I didn't like that you had to pay additional monies to get access to their direct letter mailing module and I believe there was another module that would be helpful to your biz that cost additional monies.  

Otherwise I have to have a smart phone or ipad and hope that it's getting a signal or not battery challenged. 

Is everything really included in the monthly subscription, or do they try to upsell modules and add-ons?
