    Console was just as described and after a quick wipe down, looked very nice. Packaging was a little light on material for cushioning but the console survived the trip without damage. Shipping cost was about average, overall a good value for a working console.

    These are one of my favorite styles of Skechers! They are just so comfortable with the arch support and actually helped my lower back pain just disappear. My item is as described. Packaging was very well and shipping was immediate! Great pair of Skechers for the price! This is a 5⭐️ seller and I thank you! A+++++

    Product was as described. Ordered on 1/8/25 and received it 1/18/25, which was about in the middle of expected arrival date range. Packaged very well. I would order from this seller again without hesitation.

    SB6121 PREMOD Forceware v1.4b-mod2

    This is a review of the Motorola SB6121 PREMOD w/Forceware cable modem. If you are looking for one on a stock SB6121, look elsewhere. This is a totally different beast, and NOTHING will work for you. With that out of the way: It works great for what I wanted. After reading and reading, and reading some ore, I hooked it up, changed a few parameters to let it connect, and success! Nice and fast, most options are fairly easy to understand, and it works. Make sure the "Start Mode" is set to "Online", "Tuner CFG" to MT2170, and the "PGA Type" to MT1570. If your system uses certs, READ ALOT. There are quite a few How-To's out on the Web. A negative point: It can take awhile for the modem to reboot, and then foe your router to actually get it's DHCP address/etc from the modem, and actually ...

  • You get what you pay for

    I decided to choose this product rather than the faster modem, the SB6121 due to wanting to save a buck or two and because I live in a 1 bedroom apartment. The internet I receive is fast, adequate when running through the cables, obviously less so through wifi. All in all I appreciate the modem and it's usefulness. It was easy to set up and has been great thus far.

  • Older model but still supported

    I purchased this product to be used on COMCAST. The first thing the installation tech said was that it was marked as "end of life", which meant that COMCAST would stop supporting it shortly and I would have to purchase another soon. This concerned me but upon a further conversation with a COMCAST telephone-support tech, I was told that it just meant that COMCAST was no longer selling this model and would not offer tech support for it. Having said all that, the unit is DOCSIS 3.0 compatible and should work up to 170 mbps. I am only using this modem with 10 mbps service whereas COMCAST is offering up to 2 gbps. If you are only planning to use this unit up to 170 mbps service then this unit is fine. Peace and blessings.

  • Cable Modem SB6121

    Needed faster internet and cable was the only option. Cable company was charging a rental fee but gave options for me to purchase my own cable modem. Bought this used on Ebay and works great. Very happy with the purchase.

  • Streaming demon

    Set up with Comcast was a breeze, at least as far as over the phone anyway. Works well with thru my cisco router as all 4 of my puters wired and two laptops wireless all streaming YouTube or an anime channels at same time. No choking with this bad boy. Great and I mean great buy with screaming delivery time too of only two days from purchase. Impressed I am. Easy set up, easy activation, easy money as I saves my over a "hundred dollars a year" in rental fees to Comcast.
