I have been using it for the past 1.5 years and to be honest i would buy another one as this one is performing extremely well, im not a hard core enthusiast or anything when it comes to these things and run like capacity tests and all that however from what i can tell you for my needs and what im using it for it has been working proper, also another reason i would recommend it, the price is not so far off from a GEL 100Ah with more then double the lifespan and you can actually use up to 98% +- of its capacity with out doing damage to the cells and you have BMS protection, 1 other pro, it being a lifepo4 battery i can actually use it indoors in my home office and don't have to worry about any health risks compared to LAB's, another thing i found useful was the Mains switch on the battery its self plus volt/capacity meter which you wont find on a normal battery
Point to take home for the price and what it offers i don't see why you should not consider it, however at the time of this reply i see they dont offer it any more, i see Duda has it but haven't bought from them before
Current Setup-
Battery is the exact same one you listed bought from the same company running off a 2500W 12v pure sinewave UPS inverter connected to the Grid, UPS has solar inputs as well but only using the grid to charge up the battery, think of it as a very big PC UPS.
Load currently running on it.
2x 24" Full HD LCD monitors
1x Laptop with no laptop Battery so drawing power from the UPS
1x ONT
1xRouter
2x 8 port Switchers
Expected run time: +-10Hours
