I love it because it makes strong vibrations. I had to replace it because it was making humming sound. I am happy. I have no more problems.

My other shakers wire was exposed where the shaker connects to the cord. I ordered the new shaker on a Friday and got it on Monday! Terrific! It works just fine and it is the only thing that wakes me up. I have a fire truck alarm and sometimes that doesn't wake me up. Thank you diglo! It is hard being deaf. In heaven I don't have to deal with that anymore. Thanks God.

I am most pleased with my Sonic Alert Vibrator. It is the only awakener that works for me - my hearing is quite low I was so pleased that I was able to buy the unit and have no shipping cost added. Thanks again.

Very disappointed. I purchased my first super shaker alarm about 15 yrs ago and it lasted about 8 years. I recently purchased a replacement shaker for 2 alarms and they both broke within 2 months of purchase. Huge problem with the wiring casing breaking off where it attatches to the shaker. Also purchased a new alarm with shaker about 3 yrs ago and the shaker never ever worked new out of box. Instead of revamping your website and language you should work on finding a manufacture that makes a quality reliable product

Purchased for my daughter at college. She said it works well.

This bed shaker works very well, but the wires break too often. patching the wires back together doesn't hold for long. It needs to be redesigned so the wires don't break.

very good product and shipped on timely manner.

I've been using this Shaker brand for more than 15 years. While over time, the Shaker does wear out, or the way a person sleeps can cause the wires to bend back and forth until it breaks, other than that it's very reliable. It's almost strong enough to wake up this extremely heavy sleeper consistently. I'd keep ordering from the Shaker brand, be they clock, shaker, cord replacements, etc.

The shaker is awesome at waking me up since I am a heavy sleeper and it does wears out since use it every day to get me up for work but I would order this every time for my clock which just ordered one couple weeks ago since other shaker wore out but it is awesome

My son's dog chewed up his old one, this was delivered very fast, perfect fit, works great

sounds like somebody knocking on door where I have it placed. as a truck driver they work real good

Great customer service. Thank you!

Bingo, my brain needs the heavy shaker instead of traveling clock with weak shaker after my old one with heavy shaker was worn out. Wink plus I am patting Diglo's back!

I love the Shaker. My old one quit working. I was so afraid of oversleeping while I waited. I got the new one quickly. YES! Thanks

First time used it, woke up fast because it felt like mini-earthquake hotspot right under my bed. It works a lot better than 250 watts flood light alarm since I sleep thru it sometimes. Highly recommend shaker for heavy sleepers. If it does not wake a heavy sleeper, then maybe need a bed that will throw the person outta bed!

Our son had used one for several years while in school, but it had broken and he still had the clock. I was able to order the shaker separately, which saved a ton of money. Very happy to have it working again.

My old one broke by broke wire. I had it for long time. Had to order new one and received few days later and it is working now. I am very happy with new product.

Shaker for sonic alert works very well! I recieved the product in good time. Thank you Diglo! Keep up the good work!

Works ok
