We've been using these tablets for over 6 months now without any problems - they're great! They contain the powder, rinse aid and salt so save on buying seperate products.
Convenience
They are very easy to use. No fiddling with powder spillage or having to keep an eye on the level of rinse aid left in the dispenser. Also if you have an older dishwasher that does not have a salt indicator it saves having to keep an eye on that also.
If you do big shopping trips (2 weekly or monthly) then it's easy to see exactly how many tablets are left.
Cost
The cost for a 25 pack is £1.98 which works out at approx 8p per wash. Asda also do a pack of 50 but every time we're in there they have always run out. Overall there is only about 1p difference per tablet between these box quantities.
I haven't been able to compare the cost of the tablets with buying the items separately as I haven't been able to work out how many washes you would get from the individual products. Initially though it is a lot cheaper based on the Asda range as buying these separately the cost would be over £5. (The Powder @ £1.99, the Salt @ £1.28 and the Rinse Aid @ £1.99).
In Our Experience
We use our dishwasher between once a twice a day (day 1 - late afternoon; day 2 - late morning and late night) so the box of 25 usually lasts about 2 weeks; the monthly cost being approx £4. For the sake of £4 p/m why mess with the individual items?!
The cleaning we get from these tablets is fine - I only use a normal wash setting. Obviously I scrape the plates before putting them in the dishwasher but I don't then go on to rinsing them thoroughly under a hot tap. Everything cleans fine as does all the cutlery.
Packaging
The main box is easy to open and it has an easy-close tab so it's neat and tidy in the cupboard.
The wrappers on the tablets are child-proof. They cannot be torn open but have to be pulled apart via the central seam. Our 'under the sink' cupboard is locked anyway but when my 3 year old has helped with loading I have handed him the tablet and he has never been able to open it. I have to do it for him and then watch him put it in the dispenser.
On a rare occasion a tablet has been crushed inside the wrapper so then you have to be careful to pour it but this maybe happens on average twice with each box.
Comparison
We have used other products and have been satisfied but haven't seen any major differences with the wash so will continue with the Asda tabs.
One thing we have noticed though was once we shopped at our local Co-op just for a few bits and bought their own 3 in 1 tablets. They cost 70p more than Asda and when I opened them they were packaged exactly the same. Looks to me like they were exactly the same except for costing more.
