One week of use with H153.
1. Band Lock for 4G - sometimes na-o-override ng device mismo. Locked ko na sa B1 + B3, pero minsan B40 and B28 lumilitaw. Medyo weird talaga, parang useless yung band locking
2. During most part of the day, babagsak ang speed to around 50mbps, then past 11PM aabot ng 200+ mbps
3. One time I restarted the device, using the RESTART command inside the dashboard, but upon return, I lost access to 192.168.1.1, and the only way to access it is to use the RESET button
4. Nag-add ako ng exhaust fan sa side, kasi parang hindi sumisipa yung internal fan, at talagang umiinit ang top side when downloading really big files
5. Stable naman generally, though there were at least 3 instances na may buffering ang YøùTùbé kahit na 100+ mbps; not sure if the problem is modem or YT
