I have done ALOT of heavy playing since I got it!This is my 3rd DONNER PIANO,I also have the DEP-20 which has many bells%26whistles,this DEP-100 is only piano which I wanted. It is definitely an upgrade in looks as a piano %26I love having the cover that closes as dust is the enemy of digitals. I do a lot of"all over the keyboard"playing %26 it is very like playing a real piano%26 the woodlook black case is very nice. I also have more knee room %26it has more stability than the others which sometimes move around when I'm playing a fast moving heavily chorded piece like"He"s A Pirate"(which is REALLY FAST)or"Indiana Jones theme"(which is VERY ENERGETIC). I am a hack who has been playing piano for 60 years mostly for my own enjoyment %26this piano is a pleasure to play. It has pretty good sound quality %26 I play every genre of music from the very vintage "Trip to Niagara"which is a march to classical to swing to country to elevator music to worship music to patriotic to "We Are the Champions"by Queen! Everything sounds good%26full bodied. It has excellent volume capabilities %26fits nicely against the wall. I put it together by myself in about 45 minutes%26sat down %26 began playing. Another upgrade is the sheet music holder,much better %26can be folded down. If ur sheet music is tall %26tends to bend over backwards just put an 8x10 piece of black heavy foam board behind it!A piano bench will fit but I use an antique piano stool,even a chair will do. I used black marker to touch up a few things I thought needed black. This piano has 88 fully weighted keys %26another is that the upper keys hold volume well. One con,altho says it has 128 polyphony(which is VERY IMPORTANT NOT TO OVERLOOK IN PIANO BUYING RESEARCH)it DOES occasionally DROP NOTES when playing a complicated piece. With my DEP-20s,after about a year%26 half they got a LOUD or DEAD key %26 DONNER did replace twice,but after the 2 yr warranty,forget it. I thought to try to fix myself,which I was able to do pretty easily. Most of the time it is dust,dirt,pet hair or something that makes the trouble. After watching MANY YouTube videos I bought white lithium grease,took the DEP-20 apart %26 cleaned it,regreased %26 they're BETTER THAN NEW! I was ready to trash it! Hopefully this one will be trouble free for longer but I know what to do. So just an FYI that u can FIX YOUR PIANO YOURSELF!For under $5 bucks!🎹👏so far I am VERY HAPPY with this purchase %26 have had many wonderful hours playing all my music(which I have TONS of)on this piano%26 WAL-MART DEFINITELY HAS THE VERY LOWEST PRICE on this by $100 or more! FREE SHIPPING. DONNER during the warranty period in my past experience is very accommodating for sure,but again after warranty they aren't interested at all!But now u know u can fix their pianos yourself. DONT TRASH UR PIANO til u try to fix it!Save $500 or way more!Or buy this AND fix ur old one to sell or to have more than one!
