Bests & Worsts Reviews from Amazon

I purchased this advanced cordless model for two reasons: 1. I didn't want a big bulky unit with tubes and wires cluttering my bathroom 2. Needed a waterpik that could be used while travelling This is a truly fantastic product which ultimately sorted out my gum disease and prevented major gum surgery. My periodontist was so amazed when I saw him and did a double take when he read in the file that I had last seen him 6 months previously! He hardly had any work to do I have been using this since the beginning of October 2017 The first time I used it, it alternated between tickling my gums and feeling like there were needles attacking my mouth! I couldn't finish my whole mouth due to this and my gums were bleeding in a few places I was unprepared for the PULSING water as I assumed it was just a steady stream of water One needs to persevere, as your mouth needs to get used to the waterpik sensations. It took about a week to get used to it and during this time my gums still bled. Over time, the bleeding got less and less and eventually stopped altogether as did my swollen gums First Impressions It was bit bulkier than it looks in the pictures I had to start on the LOW setting as the water pressure is quite strong After a month, I have moved to MEDIUM and am now on HIGH Some reviews have mentioned that they feel that the pressure is not strong enough, but it seems that the measure is compared to the plug in model which is understandably more powerful Having said that, I don't think that I personally could handle more pressure as on occasion, if one points the nozzle incorrectly on the gums, it still can feel like needles on the gums but this is very rare (The pressure of this portable model is approximately 75psi) The little flap where you fill the reservoir doesn't seem to be too tight when you first use it, but it works like a charm and water doesn't leak out The buttons are well positioned and one doesn't push them by mistake At first, it was quite difficult to do the inside of my teeth, until I realised that the nozzle swivels, which made all the difference In terms of travelling, it is supplied with a grey plastic "blocker" which is inserted in place of the nozzle. This prevents residual water from leaking out It is quite difficult to empty ALL the water out of it, so when travelling, ensure that it is put in a Ziploc bag as there will be a small amount of water that will leak out I use dental floss before using the waterpik. There is no special reason for this, other than I am used to using dental floss anyway and feel that this assists in removing plaque from the sides of the teeth The reservoir holds a fair amount of water (I suppose that there has to be a balance between size and capacity) I fill up between 3 or 4 times during a session which is very easy to do Although there are third party generic hard cases available, it would be nice if Waterpik had a custom hard case as an option which would be larger at one end and narrower at the other end so as not to cause unnecessary bulk in your suitcase. A hard case is a necessity as otherwise the buttons will be pressed and the likelihood of the unit being cracked or broken when you take it out of your suitcase is quite high PROS Portable Efficient Wireless charging (more on that below) Does a fantastic job 3 pressure levels Ergonomic fit to your hand CONS No proper hard case Unintelligent battery - big issue Unable to empty it completely so a small amount of water leaks out when travelling BIG FLAW!!!! The reason for only four stars is that the battery is very old technology in that if you charge it for more than four hours, the battery overcharges and will no longer hold a charge which renders the Waterpik useless One would expect that with the technology available today, the battery shouldn't be a problem, but it is It is mentioned in the user manual, but it is not highlighted and the consequences are not explained Waterpik really need to address this issue as it has the potential to damage their reputation It is worth paying a few dollars extra not to have this issue To charge the unit, place the magnetic charger on the body near the bottom (the charger is magnetised and will automatically attach to the correct spot) and it starts charging, BUT you have to remember to remove the charger as soon as its charged (about four hours), which is not convenient at all CONCLUSION Despite the battery/charging issue, I think that this is a fantastic product but would ONLY recommend it if you are willing to put up with and manage the charging of it It would really be nice if Waterpik would comment and clarify the issue
