If you are looking for a easy, fast and comfortable shaver for close-cut, this is it.
SHAVING is excellent and very smooth with foam. Whoever is having irritation or rough shave, try applying some water if you are not using with foam. If you feel the shaving performance has degraded or becoming rough, clean the shaving blades, one at a time, following the manual.
BATTERY lasts for around 30-40 minutes on continuous usage. I charge it once or twice in a month as my usage is quite moderate. It should be adequate for a normal user. If you are planning on taking it with you on your vacation, just make sure you charge it fully. It takes around 8-10 to charge it fully, if its completely out of charge. It doesn't indicate whether its fully charged or not, though it shows low battery. This might matter to some people.
MAINTENANCE is quite easy on daily basis than other shavers. Just wash it under the tap, that's it. There's complete blade cleaning guide in the manual, which may help in keeping up the performance till last. you can do this , when you feel the performance is decreased.
Overall this is a amazing shaver at its price. If you are planning to buy either AT610 or AT620, you can go for AT620, If you need an integrated trimmer to your shaver. For me it's absolutely worth the extra 3, 4hundred rupees over AT610. Else if you just needed an amazing shaver, AT610 is way to go.
