I am using the Aztech repeater and so far it is working fine. The TM provided router is located in the living room downstairs and I place the repeater on the first floor. The Wifi signal can be boosted by additional ~ 25 %. With that said I am staying in a humble 20 X 70 terrace house. If in a bigger house, then maybe need to go for other options eg. more powerful router, homeplug, etc.
