  • Fantastic Beginner Piano – Even My Baby Loves It!
Style: DDP-400 Premium Upright Piano
I couldn’t be happier with the Donner DDP-400 Digital Piano! As someone new to piano, I was looking for something that felt and sounded close to an acoustic piano without the bulk and expense—and this model delivered perfectly. The fully weighted 88 keys are incredibly responsive and give a very realistic playing experience, which has been so helpful as I’m learning technique and finger strength. What really surprised me, though, is how much my baby loves playing on it too! The touch response is gentle enough that even small fingers can make beautiful sounds, and it's become a fun, daily bonding activity for us. It’s amazing to watch my little one explore music in such an engaging way. The sound quality is rich and clear, and the piano itself looks sleek and elegant in our living room. It was easy to set up, and the built-in features are great without being overwhelming—perfect for a beginner like me who just wants to focus on learning and enjoying the music. Whether you're just starting your musical journey or looking for an instrument the whole family can enjoy, the DDP-400 is a fantastic choice. Highly recommend! ... show more

  • Not Reliable
Style: DDP-400 Premium Upright Piano
Lasted 1 year before some of the keys stopped making sound or have a delayed response. The Asurion 3 year warranty was useless.

  • Excellent Service!
Style: DDP-400 Premium Upright Piano
I first purchased the Donner DDP100 piano. I wasn't happy with the sound so I wanted to return it and get the upgraded Donner DPP 400. The problem was that I was going to out of town for 2 months so the 30 day return time wouldn't work for me. I contacted Donner through Amazon and told them my problem. They were unbelievably wonderful. They said that I just needed to notify them when I would be back and they would send me a return authorization. Last week I let them when I would be home. They were so responsive. they wanted to make sure everything went smoothly. They sent UPS over to pickup the DDP 100 and I received the DDP 400 from Amazon. As soon as it was received they refunded my purchase completely. Absolutely first class service! For an inexpensive digital piano, it plays very well. And looks beautiful. And the 400 sounds a lot better. ... show more

  • Good sounding piano, but sustain my pedals eventually quit
Style: DDP-400 Premium Upright Piano
Piano looks beautiful, plays well, the weighted keys feel nice. It wasn't too frustrating to assemble. The interface is a little frustrating to navigate, but doable. I've had this for about 3 years and it has been a good piano except the sustain pedals no longer work. For the price point, I was hoping for better quality. I contacted their support (from their website) and they did not have one for me to purchase or any troubleshooting suggestions. Their suggestion was to buy an off brand replacement from Amazon. Not the biggest deal, but it will impact the overall look of the piano (and hopefully the replacement works, just ordered it so we'll see). Edit: there is no universal pedal that will work with this piano. So I’m out of luck. I have a $1000 piano that doesn’t work. Support was zero help. Don’t waste your money. ... show more

  • Terrible Assembly Instructions
Style: DDP-400 Premium Upright Piano
Assembled this finally today after it sat for a couple of months (I just moved). If you've ever assembled anything from IKEA, you can probably manage the assembly of the piano. The assembly instructions are just an exploded picture of the piano with dotted lines (see picture) and the write is obviously not a native English speaker. Takes some figuring out to put it together. Instructions also say, "During assembly or handling, keep the device raised horizontally." Impossible to assemble and keep the keyboard horizontal unless you have saw horses or something. One set of screw holes did not align properly and could not be screwed in all the way. As a note, it is *VERY* heavy. Box it arrives in requires two people to move. One person can assemble but easier with two. So far, sound is good. Might be some issue with tuning/ intonation. Will have to listen more. Bought the piano bench to go with it. NO instructions whatsoever with the bench. It is pretty obvious but still... ... show more

  • Rich, full sound very similar to a Grand Piano.
Style: DDP-400 Premium Upright Piano
I love this keyboard, has wonderful rich sound. It has everything that I was looking for in a piano keyboard. Downside, Item arrived damaged, looks like it was dropped during delivery. The sliding lid was busted and the front of it was unattached and broken. The keyboard still works and plays well. I’m disappointed that the carriers were not more careful with the shipping but it is not the fault of the seller as that’s outside their control. ... show more

  • Donner doesn’t stand behind their products
Style: DDP-400 Premium Upright Piano
Stopped working after 2 years. Reached out to Donner and they asked for a video of the defect. I sent to them and they basically said “yup, it’s broken. But you’re out of luck since it’s been more than one year”. Expect the same from Donner if you invest in an expensive piano and it breaks in one year. ... show more
